Possible TR6060 conversion coming

[Posidon42]

I am looking into the possibility of converting the car from the beloved 6L80E to the TR-6060 from a M6 SS. I discovered someone selling the following parts from a manual SS:



6060 trans (6speed)
MTI Short Throw Shifter
Clutch pedal assembly
Clutch master cylinder with lines
Monster stage 5 clutch new, with used flywheel
Driveshaft with rubber couplers
Manual trans cooler lines and fittings


I am pretty sure I can get PatG a tune from a M6 GXP and see if he can work his magic to redefine the tune using the work he has already done with my car. The thread on the other board where someone has already done this stated that some modest rewiring was needed and he needed to keep the TCM connected to the car. Not sure why if you have a M6 tune, but I am sure there is a reason. Other than some time, eventually a 3.27 diff, and a wife with the patience to let me do this, what else would I need?

** So after almost two years after starting this thread, the car is finally done. I want to give a big thanks to Greg at Pace Performance for all the help (and patience) with ordering parts and re-ordering parts when things didn't work out when we expected. Also wanted to give a shout-out to the following people who helped make this project happen:

Patrick Guerra for his help tuning the car and getting it to work with the manual transmission
Chris White for making the BCM work with the car
Crazy Paul for his assistance with technical information
BuildItYourSelf for his help installing the transmission and helping to sort out the clutch master / slave issues
and of course all of the members here on the forum that followed this project and encouraged me to keep going


Finally a huge posthumous THANKS to Charlie for starting this website and fostering this community. Without either of those I wouldn't have this awesome car in the garage.

Not a manual swap, but this trans swap also requires the TCM to be hooked up for the car to start: http://www.g8board.com/forums/showthread.php?t=54945&highlight=

[Posidon42]

I am gathering some info from some of the other threads. Found this so far, and it seems more promising than keeping the TCM attached to the car somehow.


Probably the hardest part of the conversion is the wiring and the tuning for those that want to DIY. This is the plug for the auto tranny and everything goes into this. The manual needs a reverse lockout, speed sensor, gear indicator (missing something but, cant think of it now) all separate.

[STL_G8GT]

Goos luck if you go this route...

[Posidon42]

I am sure I will need it. I am just so sick of this auto trans and I just want the fun of knowing what gear I am going to be in. Not trying to select a gear based on how hard I push the pedal. This thing has so much torque that I don't need it to drop from 6-3 when I am trying to pass someone :(

[Greg@PacePerformance]

What did all those parts run used?
I just did a full quote for a convesion for a customer.

We're not sure if that trans will fit into the G8 or not. You may have to buy the G8 bellhousing. Also not sure on the pedal assembly.

[Posidon42]

Greg, please post the details on your quote or PM me if you don't want to make it public. If nothing else, it would be great to have the master parts list from the master himself. I believe all of those parts were going to cost me about $3k with shipping. But after burning some midnight oil last night reading about this, it doesn't seem like I would be able to use most of it. The bellhousing is different, the driveshaft needs to be shortened, and I don't know if anyone has a definitive solution for how to get around not having the TCM from my car still connected. I am pretty sure the community would welcome any thoughts you had on this.

[Greg@PacePerformance]

For a complete package for a GXP I'm at a touch over $4550.00 for all new parts.
That included an engine harness that you wouldn't need since you have an '08 and it wouldn't be compatable anyway. So closer to 4K. And a clutch is not included, but can be added.

I am pretty sure I have 99% of the parts required on my list, but some of the bolts you might already have so there might be a few extra parts.

The TCM issue has been worked out for the 2008/2009 cars. MGM GT (Sky) figured it out so you would need to contact him unless he wants to post up the info.

[Posidon42]

That sounds GRRRR8! PM inbound to you now.

[gr8lover]

Yep.... no Tehcm needed on the 4L80 either.... simple wire swap is all it takes..... same as what the camaro guys are doing also....

[WongBob]

I would be interested in this swap.

[Posidon42]

The wheels of progress are starting to turn. I need to get a definitive answer on the engine tune part of this though. I should be able to use most of the tuning PatG has done so far if I go this route.

I love my wife by the way. I told her that I could just rebuild the trans again and baby it until I get a chance to do the conversion later this summer. Her response was "But you will already have it all apart, just do it all while you are in there." Awesome spouse FTW.

[incon3037r]

I would love to do this swap

[Posidon42]

Well stand by ladies and gentlemen, I just got the green light from the spouse. Greg is going to have a nice payment coming his way. :D

[hartigan85]

Awesome. Please do a write up and post lots of pictures. I will be going this route hopefully sometime in 2013.

[Posidon42]

Will do. It all starts with a big check ;)

[STL_G8GT]

Well stand by ladies and gentlemen, I just got the green light from the spouse. Greg is going to have a nice payment coming his way. :D

That's what im talking about!!!!

[STL_G8GT]

Give me a time and place! Let me know! :-)

[Posidon42]

If I just end up getting the stock clutches, I will probably work on it next weekend. If I end up going with the manual conversion, I am going to take off work on the 19th and 20th. This will still give me the weekend to work on it if needed. Decisions, decisions... save some dough and just get it working again, or go for the gusto and make a unique car... Hmmm... Still need to find a source for that Holden manual car or the manual conversion is a no-go.

[Steve]

I kindly ask you document EVERYTHING (Hey i'm an Admin.. can I 'order' you to? haha) - Parts #'s, where to get, install tricks, etc etc to make it easier for others to perform this! This is something i'm DEFINITELY interested in seeing all the issues with the 6L80s..
Seriously it would be MUCH appreciated to have everything documented so that any other shop could basically look at 1 thread or PDF etc and get this done!

[incon3037r]

I hope this comes to fruitation and comes in at a decent cost. I've been wanting to do this too and get tons of flack from the other Vegas members about me being slower. I just like rowing through the gears, what can I say!

[Posidon42]

Greg is writing up the order for the conversion parts now. :beer: I am also having him order me the extra stock clutches and steels so I can rebuild this auto. It should be pretty bullet proof when I am done with it. Look for a rebuilt trans with stock torque converter and a Circle D 2800 stall to be in the classifieds soon :)

Same here- though in theory if you can sell your original trans + converter you may be able to recoup at least a decent portion of it

[Posidon42]

That's the plan.

First off I'm jealous, but maybe next year if this auto doesn't shape up.

With the stock clutches what clearance are you going to run?

[Posidon42]

Not entirely sure yet. I know I am going to add another set of fibers and steels and I will adjust the snap rings to bring it back to around OEM spec. Honestly, I am going to cross this bridge at a later date. I am likely going to post it in the classifieds as an unassembled unit, so whoever buys it can tell me if they want the billet intermediate shaft, the deep pan, if they want the OEM or another set of Raybestos clutches, and if they want the stock converter or the Circle D one. But that will be handled later.

On an interesting side note, PatG actually recommended that I put the stock converter back in it and that the higher stall would be more useful to someone who was still N/A but had a cam. Food for thought.

[Posidon42]

Well this may take a bit longer than I thought. Apparently the correct GXP transmission is back ordered in the US and I might have to import one from Australia. Still looking into the option of just buying the GXP bellhousing and shifter as I think we can get those. But then it would be a used transmission. Greg is still working this, I will post back in here when I know more.

[Posidon42]

Looking at possibly buying a used Camaro transmission that has been built up already. Here (http://www.tickperformance.com/tick-performance-level-2-upgraded-tr-6060-rebuild-700rwtq-for-2010-camaro-ss/) are the details of the build. It all sounds impressive, but I don't know much about the internals mentioned and whether they will be helpful. The trans has 600 miles on it right now and the current owner wants to put in a built 4speed. What do you think? I am still trying to work out what parts from the Camaro are usable and what needs to be specific to the GXP.

[Posidon42]

Things are falling into place. I am now just waiting for some money to free itself up and some time to get all of this done. Likely looking to have this done by mid summer if all goes well. Then I will be taking orders for people who want to ship me their cars for conversion :)

[Greg@PacePerformance]

I should have all the parts in very soon. Got the brake pedal and clutch fluid res and some small bolts in today :D
The last main part we are waiting on is the drive shaft.

[Posidon42]

Sweet. The donor transmission will be shipped to me after I move next month. Mmm... parts.

[Posidon42]

Greg has just about all of the parts in except for one bracket and the GXP bellhousing. And one of my possible sources for the transmission is having it removed tomorrow. I should be able to post some pics. I am probably going to get this one even though it is a 'stock' trans but has an MGW short shifter and ACT twin disk clutch.

[Posidon42]

Now accepting donations to help this build progress :)

[G8GTSBM]

What car is the trans being sourced from?

Whats the plan for the TCM?

[Posidon42]

Sourcing the trans from an SS Camaro. It is pretty much bolt in except the driveshaft and bellhousing are unique to the GXP. TCM will stay in the auto as I just need to jumper the GM bus. The car will be reflashed with a v8 manual tune from a Holden. PatG said that part should be pretty easy. Lots of things in the air still, but I think I amgoing to have a big shipment of the ancillary parts come in from Greg in the next week or so. Right now, we are working out what parts I want to order to rebuild the auto.

[stephen4036]

should be awesome when its done.

[BigV8]

Sounds great, another GT swap. I'm just wondering when a A6 GXP owner will do a manual swap.

[hartigan85]

Hopefully Greg is keeping a list of the parts that need ordered, would make it really easy when I order all of this stuff. If you don't mind me asking how much was everything minus the transmission and clutch?

[Posidon42]

Yes, Greg has a list of parts. As for the final cost, I don't know for sure yet. I am ordering several parts that may end up being interchangeable with the Camaro parts. Once I get everything in, I will have a better idea of what parts are required. From my searching, this will only be the second GT converted to manual. I am definitely going more of a budget build than the other conversion.

[Posidon42]

Sounds great, another GT swap. I'm just wondering when a A6 GXP owner will do a manual swap.

The parts list needed will be almost identical.

[Greg@PacePerformance]

Once we are sure what parts can be reused on the GT ie bolt and small parts That will help with getting a final price. It will also depend on what you get used like a transmission and other parts from a Camaro owner.

[hartigan85]

Ok sounds good. I will be trying to source a transmission from a camaro, not sure what else is interchangeable but hopefully you guys will be able to help with that when posidon42 does his. I am gonna try and start ordering parts little by little until I have everything.

[BigV8]

What are you doing about the tranny mount cross member? Dave on the other forum said he had to modify his because he couldn't get one in the US.

[Posidon42]

Ordering one from the GXP. Greg has it taken care of :D

[BigV8]

Ordering one from the GXP. Greg has it taken care of :DGreg, what a great guy :)

[Posidon42]

Parts ordered today. Will have everything in by mid May. Timing is unfortunate but we are moving and I don't want the movers to lose any parts, so I am having them shipped to me after the move. Also put in the deposit for the trans this morning. It should also come in mid May. For those interested in doing this, I am estimating the entire conversion will cost me less than $5k. And that is probably on the high side, but I am adding in the fact that I am also buying a 3.45 diff to go with the new trans.

[incon3037r]

SUBSCRIBED
I'm waiting to see how this turns out as well as the parts list!

[hartigan85]

I am crazy excited to see this happen and get a true list of whats needed. I will be doing this conversion, just have to get the wife a new car first since she wont drive a manual. That's also another plus for doing the conversion. lol.

[Posidon42]

Haha. I don't want to break up any relationships. My wife keeps threatening to cut off my internet access because of cash robbing forums like this :)

Update - my parts from pace performance should be here on Monday! Trans is still probably another couple of weeks off.

[hartigan85]

Nice. Did you order a new tr6060 or find one out of a Camaro? Have you figured anything out with the wiring for the reverse lockout or reverse lights yet? I never heard back from the guy who did the conversion on the other board. I'll tell you what, if you send me all the parts you have I will install it on my car and figure all the wiring out of you. :thumbsup: haha.

[Posidon42]

Getting a pull from a camaro. As for the wiring, I will figure that out as I go. I didn't hear back from the other guy either. Still need to clear out some garage space for all the new parts!

[hartigan85]

I was researching the MG9 transmission that GM puts in the ZL1 Camaro and CTS-Vs, I think I will go that route when the time comes just because it is rated at 551 lb-ft tq.

[Posidon42]

Sounds good. The trans I bought was already upgraded by tick performance to handle 700 so I think I will be ok.

Link: http://www.tickperformance.com/tick-performance-level-2-upgraded-tr-6060-rebuild-700rwtq-for-2010-camaro-ss/

[hartigan85]

Hell yeah that thing should be pretty much bulletproof. Damn now I'm thinkin I should find a used Camaro trans and have Tick build it. Might work out cheaper and definitely better.

[Posidon42]

PARTS!!! Pics later ;)

[Posidon42]

15276

One of the best parts in my recent shipment from Greg. :D

It will probably be another couple of weeks until me trans gets here though. No need to start making a mess until it gets here.

[hartigan85]

Very nice. Are you gonna run all the stock shifter parts or go aftermarket shifter? Did you decide on a clutch yet?

[Posidon42]

Going to run aftermarket shifter parts. I can remember what brand it was off the top of my head. And the setup I bought comes with the ZL1 clutch and the new large bore master cylinder.

[Darkmanx]

when you figure it out write a how to so i can do it too.

[rocket69GTP]

Sounds like u went with the adapter plate katech makes...

[Posidon42]

No, the ZL1 clutch should work fine, but I have to remove the spacers on the slave cylinder to get it to work. If nothing else, Tick Performance has a set of spacers that I can use to adjust it to the exact tolerance required.

[rocket69GTP]

Oops, ZL1, not ZR1, that's my bust.

[Posidon42]

No problem, and my trans should be I'm the mail sometime next week!!

[solty]

You are my hero....I want to do that so bad. That 6L80E is just a thorn in my side.
I will be following this thread closely.

[Posidon42]

Payment for trans sent yesterday. Hope to have everything in by the end of next week :D

[Frostopsy]

I'll watching to see how it goes. Good luck!

[Posidon42]

Trans is out and should ship after my check clears his bank next week. Clutches and most other parts will be shipped on Monday. It is starting to come together.

[Posidon42]

Trans is in the mail!

[Posidon42]

ARGH more delays... FedEx picked up the trans today. Unfortunately, it weighed in at 168 lbs and FedEx Ground's limit is 150 lbs :( So... now I get to try "rape you with shipping costs" = UPS...

I looked into some of the engine / trans shippers I have used in the past and they were more expensive. Oh well, it will all come together eventually right?

[dandragonrage]

So send it in two boxes... take something that weighs 18 or more pounds off of it and send it separately. Unless it would be cheaper to just find someone to ship it whole (freight?) compared to two packages with FedEx/UPS/whatever... BTW, if you have a shipping dock at work that you can use, it may be cheaper to have it shipped there (though you'd obviously have to deal with getting it back to your house... personally, I did that exact thing one time for an old car of mine; I took out the passenger seat the day before it arrived and just drove with the new transmission riding shotgun. heh. Oh, and I was lazy and left it there for 4-5 days, haha.

[Posidon42]

Maybe it will go out on Monday... I told him to either take it to ups as is and I would eat more shipping costs, or take off the bell housing and send it back through FedEx.

I feel like I have been f'ing with shipping this trans forever.

[Posidon42]

Need to know what else I can take off this trans before shipping. It is 170 lbs with a Rubbermaid container right now. He is going to try to take off the bell housing tomorrow but I doubt it is going to weigh 20 lbs. If I can get it to 150, shipping is about $125. Anything over that and it has to go freight which costs 4x more. The best freight quote I have is almost $450 :(

Need some help!

Maybe I can convince a local store to let me use their shipping dock as the residential service is ~$95 at each side. And this isn't even for a lift gate!!! Shipping companies suck.

[Posidon42]

Anyone? I am not sure how much I can ask him to take off this trans to get the weight down.

[RWD-V8]

Bell housing should get you there... that thing is stout. Drain the lube if you need more?

[dandragonrage]

Yeah, I would have guessed the bellhousing to give you all 18, if not at least very close...

[Posidon42]

Well, we'll find out later tonight when he takes it off. Supposedly I don't need it, but it would be nice to have the Camaro bellhousing just to make SURE we can't use it.

[Posidon42]

Just weighed the replacement GXP bell housing and it was around 9 lbs. :(

Looks like I will be looking at a freight shipper. At least I found one company that will do it for around $300. Still quite a bit off from what normal shipping is.

[Posidon42]

After much ado, the trans should be on a truck today. :)

[Posidon42]

It's finally on the way!

[G8GTSBM]

Nice!

[Posidon42]

Cleaned out the garage and put down two coats of a one part epoxy on the garage floor. Just in time for the disassembly mayhem.

[Posidon42]

Trans came in today!!! Might be able to start working this weekend.

Otherwise good luck with the swap!

[Posidon42]

Well I may have hit a speed bump with this project :(

My parents are moving out here to be near the grandkids and they were supposed to close on their house today. Two hours before they were to meet at the agents office, the bank called and told them that they miscalculated something and they were no longer approved for the loan. So now I have to find a way to squeeze five vehicles and a 16' trailer into my garage and driveway because we aren't allowed to park on the street overnight.

Damn the luck, just as I got everything in, this happens :(

I am sure it will work out in the long run, but I am going to be spending my evenings and weekends finishing the basement instead of working on the car. I am still hopeful I will have it done in time for GONE but I may be pushing it.

[bracketracer]

My fingers are crossed for you! I really hope to get to see this car at GONE. Hope you, and your family, are safe from the fires.

[Posidon42]

Thanks. The fires are pretty far away and we had some rain last night so that helps a lot. I will get to it when I have time, but it might be a little while.

[Posidon42]

Some possibly bad news from Greg.


Well here is a little good and bad.
Ok you know the Camaro trans you got has the longer bellhousing. Well after doing much thinking about it, when you have a longer bellhousing the trans will have a longer input shaft that will not work with the G8 bellhousing.

I think if you keep the Camaro housing on that will put the shifter too far back and the GXP drive shaft would be too long.

You have two options that I think will work.
You can switch the input shaft on the trans to one from the G8. I don't know what is involved in that but I think it would be pretty hard w/o knowing exactly what you are doing.

OR

you might be able to use the T56 crank bearing instead of the TR6060 bearing. This will allow the input shaft to sink deeper into the crank. I'm pretty sure that will work but you would have to install the bearing and then install the trans to check I think.

-Greg

I am going to measure the height of the bell housings and see how far off they are.

[Greg@PacePerformance]

If the Camaro bellhousing is only about 1" longer than the G8 bellhousing then the 14061685 pilot bearing should work along with the G8 bellhousing, essentially turning the Camaro TR6060 into a G8 TR6060 w/o changing the input shaft.

[Posidon42]

:(

The camaro bell housing is almost 3" longer. I re-read through the build on the other forum about this and he actually bought a GXP trans. Which is probably why he didn't have this problem.

[jonnynadeau]

Which is it, 1" or 3"? This is where a guy can't lie about his shaft length...jk!


iPhone, Tapatalk, enough said!

[Posidon42]

Definitely 3" longer. This may be a deal killer as I will have to swap out the camaro input shaft for the GXP one. Though I can't buy one anywhere...

[Posidon42]

Some good info for the archives, but the future of this conversion hinges on Greg/CP getting me some trans parts. http://forum.grrrr8.net/showthread.php?t=32444

[Darkmanx]

or just buy a gxp transmission

[Posidon42]

Not available. No stock in the US and I don't want to think about getting one from aussie land.

[Frostopsy]

Before you go chasing parts in Aussie land, I think you should try to mock it up and see if it fits with all the Camaro stuff. If it does an easier solution may be to have a machine shop modify/make new linkage. Its worth a shot.

[Posidon42]

It isn't that it won't fit, but the shifter will be in the cup holders.

[Darkmanx]

Not the worse problem ill take that to get rid of this Damn 6l80

[Greg@PacePerformance]

You said the Camaro housing was 3" longer than the G8 housing, but that did not include the front plate on the GXP trans.
I have to crawl under mine today so I will take a measurement with the front plate included and the total length (I wish I would have done that when it was out of the car)

[Frostopsy]

It isn't that it won't fit, but the shifter will be in the cup holders.

That's what I'm saying, isn't there a way to modify the shifter linkage to just relocate the shifter? Maybe talk to a machine shop about modifying or fabing some new linkage. Its worth a shot perhaps.

You are right, I just measured the housings. Let's hope your measurements are similar to the camaro.

I know that we do this in the ls swap 240sx world, look at sikky swaps to see theirs.

[Anon]

I have done this swap in both the 240 and the rx-7, but that is completely different. In those situations the engine and trans are bought together as a set usually and the motor mounts are aftermarket and made so the engine and transmission fit correctly in the car.

Here the engine is staying where it is, the appropriate trans isn't available, and the new trans doesn't fit correctly. I doubt anyone would want to make custom mounts and move the engine forward a couple of inches to make this conversion work. At that point you would make the car handle worse and cause fitment issues elsewhere in the car.

[Posidon42]

I haven't given up yet, but the goal is to use all factory parts if possible. I will head down the custom parts path but only if absolutely necessary.

[Frostopsy]

Dave GA had both bell housings. Maybe you can ask him about the differences? http://img.tapatalk.com/a6937996-555f-9656.jpg

[Posidon42]

Man that looks promising. That trans cover piece looks pretty thick. If it is around 2" or so, we should be able to adjust with the pilot bearing. Where did you get the picture?

[Posidon42]

Greg, looks like I need that trans cover plate to be sure. And probably whatever wiring/sensors plug into it.

[Greg@PacePerformance]

Sorry I keep forgetting to measure for you.
I'll order the cover plate and it should be here from GM on Monday.

[Frostopsy]

Dave GA on the other G8 forum. He put it in the write up he did on his TR6060 swap.

[Posidon42]

I am very familiar with that thread, just didn't remember the pic.

Greg, sounds good. I just need to transfer my direct deposit to Pace :)

[Greg@PacePerformance]

I did a quick measurement just now.
Looks like the GXP bellhousing & the the trans front cover plate = just over 8"
What is the Camaro bellhousing size? You might not need the GXP bellhousing.

We might get lucky :)

[Greg@PacePerformance]

Went out and did a better measurement.
Looks like the GXP bellhousing is 5.75" in length and the transmission front cover plate is 2.25" making a total 8"

[Posidon42]

The camaro bellhousing is 8.75". This just might end up working out with the camaro trans as it sits, though we might have to get creative with the pilot bearing and properly adjusting the clutch. Likely have to get some custom shift linkages and, if we use the stock camaro trans, the driveshaft might have to be shortened a bit too. Still not as bad as trying to order unobtainable parts.

What would most likley work is for you to use the G8 bellhousing and transmission front cover and the Camaro input shaft. This would make the input shaft 3/4" longer than normal and within specs to use the pilot bushing that sits further into the crank. That would correct all the other issues with the linkage and driveshaft, and trans cooler lines.

[Posidon42]

Sounds like a good plan. Sending you a pm.

[Steve]

So basically:
Camaro Trans = Headache
GXP Trans (if you can find one) = easy peasy?

[Darkmanx]

guess you gotta buy a whole new gxp to find a transmission.

[Posidon42]

So basically:
Camaro Trans = Headache
GXP Trans (if you can find one) = easy peasy?

Not necessarily. We already knew that I had to buy the different bellhousing and buying the trans cover isn't that big of a deal. And there are lots of Camaro transmissions lying around where there are no GXP transmissions available. So if I have to buy a couple of parts and swap some stuff out, it isn't that hard. As long as it works in the end :D

I might have to adjust the shifter linkage for the aftermarket shifter I bought to make it work, but I am more concerned about getting it to mate properly first. Then I have to start messing with the clutch alignment, etc.

[hartigan85]

It blows my mind that GM has no GXP transmissions stateside. What would they do if someone had a problem with there transmission??? Sometimes it really sucks owning a car that was made in so few numbers from a division that doesn't exist anymore.

[Greg@PacePerformance]

So basically:
Camaro Trans = Headache
GXP Trans (if you can find one) = easy peasy?
I'm pretty sure right now that the Camaro trans will work in the GXP with the addition of the GXP bellhousing and front cover plate. (but we will see soon)
If it works that will be the way to go if the GXP trans is not available.
If it works the 2 part will add about 550.00 to the cost of the transmission, couple that with buying a used Camaro trans and all the extra parts you will end up cheaper than the GXP trans alone if you could buy one.

It blows my mind that GM has no GXP transmissions stateside. What would they do if someone had a problem with there transmission??? Sometimes it really sucks owning a car that was made in so few numbers from a division that doesn't exist anymore.

GM would have someone rebuild it would be my guess or wait a very long time for a new one.

[hartigan85]

Guess I will have to hold off on doing the conversion until the SS sedan comes over. They should have the same manual trans setup I assume.

[Steve]

Now, based on CP's post - is the Camaro Trans exactly the same as the GXP, since it said something about heavy Duty etc?
Is there anything that needs to be done to these TR6060's to beef them up internally, or is just a factor finding a better clutch? (and would any work? or only GXP ones?)

[Greg@PacePerformance]

From what I have seen so far is that the GXP and the Camaro trans are the same except for the items above (bellhousing, front plate and input shaft), but time will tell as soon the part arrives.

The TR6060 is a pretty stout trans, although some of the Camaro guys have maxed them out and sent them to places for upgrades. But if your plan is drag racing a stick isn't the best option any way :)
I'm far from puttting down tons of power, but mine is doing just fine with putting 570hp and 509tq to the ground, but that is running stock size tires. I'm sure if one were to change to a sticky tire that might change things some, and that is why GM uses the upgraded TR6060 in the ZL1 and CTS-V

[Posidon42]

So... Greg had some good news and some bad news for me today. The bad news is that the trans cover from the GXP won't fit the Camaro transmission. Apparently there are some things in the GXP trans that aren't in the Camaro trans so it won't fit. :( The 'good' news is that the GXP transmissions are now back in stock and available for purchase. So either way, I need to sell my Camaro transmission. Then I will look into whether I am going to continue with this project or just go back to the auto and return all of these parts. This is disheartening for sure and it pretty much guarantees I won't have this done for G.O.N.E. like I wanted it to be.

[hartigan85]

Where did you find it at? Whats the part number for the GXP trans?

[Posidon42]

Greg said they can order it now. Hoping to offload the extra camaro parts to be able to buy the GXP version.

[Darkmanx]

how much is the gxp trans?

[Posidon42]

~$3k

[Darkmanx]

wow not bad still cheaper than getting a built 6l80

[Posidon42]

Right. Just wish they were available three months ago. The car would be done by now :)

[Darkmanx]

Hurry and do the swap and do a write up so I can copy

[Greg@PacePerformance]

I got this back from Tremec.
19210316 (I found this part in the parts catalog on Friday but there was no picture listed an it was in the incorrect parts group.
19210316 - $269.00

The front adapter that has the pump assembly is a TUEP8269 / 19210316. We only offer this as a complete assembly . CUCM8269 is the raw , unmachined casting. The TUCM2030 / 89059423 is the bell housing ....I don't think this is what you were looking for. Your GM dealer should be able to get the adapter assembly above from the # I provided.
As a caution, when installing the pump-equipped housing, you will need to align the pump drive pin with the drive slot machined in the cluster gear end. Not doing so will cause the adapter to not attach fully/ properly and could cause permanant damage to several components. Lastly, because you have changed a major casting assembly, you will need to check & set the input & cluster gear end plays( shimmed behind the bearing cups in the adapter housing). ( .0005 -.0035 inch loose)
I hope this helps.

[Posidon42]

Darn you Greg! I had just written this project off then you come in and resurrect it for me. :D Oh, and I double checked today and I do have the correct 6 bolt flywheel, so this project should be good to go. The car is up in the air and I took most of the exhaust off tonight before I had to come in. I will call in tomorrow to order that trans cover.

[cynic783]

:thumbsup: this is good to hear!

[Posidon42]

The trans cover should be in by the end of the week and it should be in my hands early next week. I plan to take the car and the auto apart this weekend and see if my suspicions are confirmed about the clutches.

[Greg@PacePerformance]

Cover is in and it is the correct one. :first:
Still haven't heard back from GM. I got with Tremec and they told me which GM part number to order :D

[Posidon42]

Did some more searching and it looks like this should be a pretty easy swap as long as I don't have to change out the input shaft.

http://www.gmhightechperformance.com/tech/ghtp_1203_lt1_t56_adaption_new_version_conversion/index.html

Just need to figure out how to measure the tolerances for those bearing cups and which shims I need to get.

[Posidon42]

More good info from another company that sells an SFI adapter plate for the transmission. Some good installation tips in here too:



THE PLATE AND BELL IS EASY AS LONG AS U STAND THE TRANS UP TO DO IT. THE INPUT IS THE ONLY THING U NEED TO CHECK. BEFORE U PULL IT APART MAKE SURE U HAVE NO UP AND DOWN PLAY WITH THE INPUT, IF THIS IS TRUE THEN JUST REUSE ALL THE SAME SHIMS. (NOTE 1) PUT THE FRONT PLATE ON WITH 4 BOLTS EVENLY SPACED LIGHTLY TAP THE INPUT WITH A HAMMER DOWN TO SET IT AND CHECK INPUT PLAY IF ITS GOOD PULL IT APART ( NOTE 2) MAKE SURE U LINE UP THE PUMP WITH THE CLUSTER GROOVE SEAL IT DONE


NOTE 1
WHEN REMOVING THE FRONT STOCK BELL PLATE MAKE SURE THE INPUT DOSE NOT MOVE UP KEEP PRESSURE DOWN AS U LIFT THE BELL OFF.
NOTE 2
U MUST SWAP OVER THE OIL PUMP AND REPLACE YOUR PUMP HOLDING PLATE WITH OUR PLATE BLACK LINE UP NO SNAP RING NEEDED SWAP OVER ALL THE FITTINGS, PICKUP AND PRESSURE RELIEF VALVE.


I believe Note 2 is invalid for our application as I said I had a 2010 SS Camaro transmission (which is true) but the GXP adapter plate has different parts in the cover plate. That's why Tremec only sells the GXP cover plate as a complete unit.

This doesn't sound too bad, I just need to get the parts in and start working on it!

[Posidon42]

Trans cover plate and the new pilot bearings came in today. Hope to get some time this weekend to work on it. Busy at work these days. :(

[Darkmanx]

I really hope this works so I can do it too

[Posidon42]

Just get the GXP trans. Costs a bit more, but at least you know it will work. The jury is still out on this project.

[Darkmanx]

i would if i knew what to do

[Blanky]

Someone run up some legit price numbers on a gxp manual conversion for our GTs...

[Posidon42]

Lol. I am learning on this too. The good thing is I will probably have some extra parts when I am done. I ordered the 'correct' parts from Pace and I have the original parts from the Camaro pullout.

Good news tonight! I finally pulled the trans out of the car. Still have to get it out from under the car as my jack is too short, but I have solved that problem in the past. Also, it looks like there might be a chance we can use the automatic driveshaft. The manual is probably 1.5 inches shorter when fully compressed. When I get it all put together, I am going to see if the auto shaft will work.

[Posidon42]

So I am well underway with the project. The auto is out, the ZL1 clutch is in, and the shifter is in. I was working on the most egregious part of this conversion which I feel is mounting the clutch pedal. Taking the brake booster out was a byatch!! Anyway, now I think I have the wrong clutch assembly. The part shown in the GXP parts catalog is 92233420, but the clutch I have is 92247632. I believe this was intended for a Camaro... I might be able to make it work, but it doesn't fit the same. The front "snout" seems to be about 1/4" longer than what would like to fit in there. Based on this, I am also not sure how I am going to make the master cylinder work... :(

Guess I will work on adapting the GXP parts to the Camaro transmission tonight. If all goes well, I should have most everything buttoned up this evening, but I am not going to push it. Taking a beer break right now.

[Posidon42]

And while I am working on all of this, I just realized that I don't know how to let the car know that the clutch is in. PatG already sent me a M6 Holden tune with my engine stuff incorporated, but the ECU should still be expecting a signal from the clutch sensor that lets it know it is ok to start the car. If anyone has any thoughts on how I can find the wiring diagram for this part, I should be able to make an adapter to 'get-r-dun'. Won't be pretty, but it should work. Details, details.

[Posidon42]

Well boys and girls, it just won't work. The gears and bearings in the top of both shafts in the Camaro are much larger than the GXP. I will post some pictures later tomorrow. Tomorrow, I am going to try to put the Camaro trans as it sits into the car. This will let me know if any of the other parts will have to be modified (driveshaft, shifter linkages, trans support, etc. If there are too many changes, then I will either 1) sell this thing and buy the correct GXP trans (just more money...), 2) the refund from sending back the trans cover and bellhousing might cover the cost of modifying the above items, or 3) scrap this whole project and just fix the auto again.

[WickedMom]

Bummer...

[Posidon42]

Lol, understatement of the century ;)

[Darkmanx]

Th400?

[Frostopsy]

That's a major bummer man. Sorry to hear that.

[Greg@PacePerformance]

Weird this is from Tremec

Rad,
There are a few differences to note with the Camaro VS G8 units:
1)The Camaro input shaft is closer to an inch / 25 mm longer than the G8.
2)The Camaro has an integral bell/ adapter casting that is approx. an inch /25mm longer than the G8 bell/ adapter combination.
3) The CSC mount face on the Camaro is only .4 inch/ 10mm deeper than the G8 You will have to carefully set up the CSC to function correctly.
I hope this helps. Good luck with your project.

Let me know I can help in any way.

[Posidon42]

Start processing some RMA paperwork ;)

Yea that isn't going to work. :(
Are you going to test fit it to the car still?

[CanadianEh]

Machine it?
If thats all thats holding you up, it will still work very easily

[Posidon42]

No machining for me. I would rather send these parts back and get the GXP trans. I don't want any unique parts on my car if I can help it.

[Posidon42]

Yea that isn't going to work. :(

Haven't decided yet. I took yesterday off to hang out with the kids. I probably will as I don't have anything else to do on the car now.

[spider1701]

Should the Gxp manual fit with no issues other than tuning, cutting for pedals, and wiring? Any idea of total cost of going that route?

[Darkmanx]

4-5k the gxp trans is 3000 dollars alone

[spider1701]

Ok but that does make it a possibility with upgraded clutch for high horsepower, a built trans is the same kind of cost, and a blown clutch should be much cheaper and easier to repair in the future. Sure you loose some time at the track but the fun of rowing your own gears will offset that for some people.

[Greg@PacePerformance]

No machining for me. I would rather send these parts back and get the GXP trans. I don't want any unique parts on my car if I can help it.

The only other thing I could come up with is getting with Rockland Standard Gear again and try and buy their front plate w/o the Quicktime bellhousing. I'm guessing they are using the front plate you have an doing some machine work to it to fit the Camaro trans.

I have an RMA number ready for you. I just need to know if you will be shipping everything back or just the front plate and bellhousing :D so you can get the GXP trans ;)

You will need to wire the switch to the ECM. You will have 3 pins.
Pin "A" on the switch goes to pin 54 on the X1 connector on the ECM - (5v reference)
Pin "B" on the switch goes to pin 26 on the X1 connector on the ECM - (CPP sensor signal)
PIN "C" on the switch goes to pin 42 on the X1 connector on the ECM - (low reference) ie ground
Both ECM's (08-09 and 09.5 use the same pinouts)

If you need the connector for the CPP sensor it is - 88953364 - $68.72

It is the same as the brake pedal connector and used on many other cars so it could be found at a salvage yard also.
Cobalt, Cruze, volt, impala, Monte Carlo, Corvette, Malibu, G5, Torrent, Solstice, Grand Prix, G6, Regal with various years for all. I know MoradPartsCompany.com would have the one from the Cobalt and Wbody

[Posidon42]

Should the Gxp manual fit with no issues other than tuning, cutting for pedals, and wiring? Any idea of total cost of going that route?

Lol, there are lots of issues. Just depends on how professional I want the end product to look. The other G8 that has this done has a switch wired to turn on the reverse lights... I just hadn't anticipated all of these little issues. Other than getting the mechanical parts to work, I still have to: wire the clutch (probably just make something up); fabricate a mount with a micro switch so the reverse lights will work and possibly dual function as the reverse solenoid lockout; and I am sure there are about 20 more things behind this.

I have to tell you that the biggest PITA so far was getting that brake booster out.

[Posidon42]

Lame

True, but he has a good point. Not counting the raw cash I have spent into this project, I have also lost three out of the last four seasons of use out if this car with it not working on its own power. :(

[Posidon42]

-Greg

I guess I forgot to post that the Rockland housing was half the price of the GXP transmission ;) I am not that hard core about using the Camaro trans. Unfortunately, I am swamped right now at work and probably won't have a chance to mess with this for a couple of days. I would still like to see if the Camaro trans could work, but right now I am about to cut my losses and just put the car back together.

[Frostopsy]

True, but he has a good point. Not counting the raw cash I have spent into this project, I have also lost three out of the last four seasons of use out if this car with it not working on its own power. :(

He does have a point, but to me, the advice isn't in the spirit of being a DIYer, hot rod enthusiast, etc. The same could be said for people trying to just go fast. Why try to race a four door, heavy car with limited aftermarket parts when you can get a C6, S197, or whatever.

Thanks for giving it a try for the rest of us. Hopefully you can get through this mess and get the car up and running.

[Posidon42]

It's looking like I might have a local buyer for the trans. :)

[Posidon42]

Trans is sold. Buyer is picking it up this weekend. So now the question... To continue or not to continue.

[Greg@PacePerformance]

Continue! But I am biased :D

[Posidon42]

Lol. What's the lead time on that GXP trans?

[Frostopsy]

Do it!

I talked to you about the parts a few months ago. I think that would be a great deal. I'm waiting for a few brave souls to get in done in their garage before I commit.

[MIEngineer]

A manual trans makes a G8 feel like a totally different car [obvious auto to manual differences aside, I mean just overall]. Nothing like factory parts.

Only reason I went GXP was really because of the manual trans.

[08G8V8]

I vote you continue on, for the benefit for the rest of the community. I know it's been done once before over on the other board, but with you doing it yourself, you can better document all the issues.

But in the end, getting the car up and running as soon as possible is very appealing, and it sounds like you've had more than your share of downtime and just want to drive your car.

Best of luck.

[Posidon42]

I found out today you can get all of the trans connectors on ebay for about $30 shipped. Comes with vehicle speed sensor, reverse lockout sensor, and the skip shift wire. Then these just have to be connected to the wiring harness and everything should work. It still looks like I will have to fab up a mount and a micro switch to get the reverse lights to work. I am going to wait to make sure this guy pays me tomorrow and picks up the trans on Sunday. If all goes well, then I will send back some of the parts I have already and order the GXP trans.

[Steve]

If there's a complete package we can buy (or even a list of part#s etc) I'd definitely be interested!

[Greg@PacePerformance]

I will put together a kit for the conversion once Steaven lets me know what parts are duplicated that I sent him, with what was already on the car.
I would rather not post a parts list at this time as there are 50+ parts needed, and it takes some time and knowledge to dig them all up.

The best part is you can do it in stages if money is tight. It will cost you more in the end because of shipping, but you can spread it out. The trans is the most expensive part at slightly less than 3K, but the rest is mostly all little inexpensive parts considering.

[Posidon42]

Like Greg said, the trans is the biggest unique part. The only other parts that is unique is the shifter boot. The shifter itself is the same as the camaro, but the GXP boot won't work with a stock camaro shifter. You need the press on style. My donor shifter had the MGW shaft already on it when I bought it so the GXP shifter fit great.

The jury is still out on the driveshaft. The new one is shorter than the stock one, but I don't know how much that matters yet.

The other parts like the clutch, master, slave, pedals, and trans connectors should fit if you have a donor.

Don't worry, I am documenting the process and will post up a write up when I am done.

Greg, which pilot bearing is the right one to use with the GXP trans?

[Greg@PacePerformance]

The large pilot bearing is the correct one. Part number 12557583

[Posidon42]

So I assume that means I need to use the spacer behind the slave now.

[Posidon42]

Had a nice little delivery today http://img.tapatalk.com/4b473119-22a5-fff2.jpg

[cynic783]

Very nice! Is that the camaro t6060 or the GXP t6060?

[Darkmanx]

pretty sure its a gxp

[Posidon42]

Yes, it is the GXP. Probably won't have a chance to work on it till next weekend though.

[Darkmanx]

cant wait i hope it works.

[Posidon42]

Lol, me too.

[Frostopsy]

Nice, looks like a work of art!

[Posidon42]

If anyone has a source for a clutch pedal, I need one bad. Everything else is in the garage but I don't want to put the trans in without having run all if the wiring and hydraulics.

[Posidon42]

Clutch pedal assembly is on the way! Should be here tomorrow afternoon. Will give me time to wire in the trans sensors and finally install my wideband O2 sensor.

[Posidon42]

Made up my own connector for this, but I am not sure which of the pins you are referring to as A-C. Using the image below, which is pin A?

16479

[Posidon42]

Installed the clutch pedal today. Wasn't too hard and I used the gasket and the grooves in the firewall as a reference. As it turns out, I probably installed the bolts about 1/2" too far to the drivers side of the car as the bottom bracket for the clutch assembly is touching the support in the footwell. I hope it won't be a problem, but I am going to need to install some foam or something in there to prevent the parts from wearing on each other. Going to install the wiring and the master cylinder tonight/tomorrow.

[Greg@PacePerformance]

Your connector should be labeled with the letters, but if not from left to right in your above image. C - B - A

[Posidon42]

Sorry to keep everyone waiting, but I am getting a lot of pressure from the future parts approval authority to finish the basement. I am going to hire out some of the work, but I am hoping to get the framing done this weekend. And yes, I have a permit ;) Sucks because I am pretty sure I have everything I need to get this done, just need to do the wiring for the connectors and start putting parts back in the car. But it will have to wait. Here's to maybe driving the car by Thanksgiving... :beer:

[rocket69GTP]

Has there been any forward progress on this? Seems like this tranny would withstand a lot more HP and looking at secondary possibilities with where I am going ;)

[Posidon42]

Actually, I am going to start working on it again tomorrow. The wiring is intimidating me and I really don't want to mess anything up with the ECU. However, if I take much longer, I fear Greg may not let me send back the stuff I don't need ;)

[Posidon42]

Some progress to report (finally). Finished installing the new brake pedal and all of the clutch parts yesterday. Bought some more wire this morning to run the trans sensor wires to the ecu. Still not sure how I am going to add everything, but that is why it's a project :)

Going to finish installing the wideband before I button up the interior and start putting the fun stuff back together. Taking some good pics of the process and taking lots of lessons learned. Like taking the brake booster out is a PITA!!

[Zodiac]

Good to hear that you didn't give up. Keep us updated.

Ordering a full GXP engine harness. Should have done this with the original parts order. Might need to look into an aftermarket pedal set as the camaro clutch pedal is just black but the GXP one is black and silver. Sold my truck so the build is back on!!

Wiring harness and trans rebuild parts came in yesterday. Lets hope for some progress this weekend!

Might be finally moving that way soon!!

[Posidon42]

Sorry for all the delays, but we moved to a bigger house two weeks ago and had to deal with all that drama. The good thing is that I made some good progress yesterday and removed the existing wiring harness. Took me about three hours to do it but I was taking my time and tried to make sure I didn't mess anything up. I took a bunch of good pics that I will put in my transplant documentation when I am done.

So far I have only noticed a couple of differences in the harness. The biggest one being that the oil pressure sensor connector is COMPLETELY different than the one on my car. Not a huge deal, I am just going to cut the current connector off and splice it into the new harness. But it does kinda negate the underlying reason whey I bought the entirely new connector. The other thing is that the connector going to the starter has an actual connector in the new harness, where the old harness only has an eyelet connector which bolts to the starter.

Procedurally, the biggest hurdle was that I had to take the water pump assembly off because the wiring harness was lodged between the maggie and the back of the water pump. Not sure if this will be a required step if you don't have the supercharger, but it was something I had to do.

Planning to put the wiring harness back together today but it will probably take me longer as I have to take the clutch pedal back out so I can put the 'correct' connector on it. Sounds easy right? Wrong. To get to the clutch pedal, you have to take off the brake pedal and the brake booster, and unbolt the clutch pedal from the engine bay. THEN you can take the clutch pedal out and access the wiring. For anyone who is going to attempt this later, do yourself a favor and do it right the first time.

Lastly, there is one connector on the new harness that I couldn't positively identify. I am 99% sure that it is for the clutch pedal, but it seemed farther down on the harness than it should be. I was able to confirm the three new connectors for the transmission but would appreciate if one of the parts gurus could confirm that this is for the pedal.

I wonder if the newer 2009.5's would have the same oil pressure sensor connection since the share the same computer as the GXP's....
Seems as though this is turning out to be a bit of pain to put together.

[Posidon42]

Labor of love :)

It's all about trying something new. I have never been one to leave something stock for long. Just ordered a new server too since I need something to play with after dark :)

[Posidon42]

Might be finally moving that way soon!!

Sounds great. It would be cool to meet some folk from the forum. I missed out on the meet last year and will probably be deployed during the meet this year :(

[hartigan85]

Glad to see you are starting to make some progress. Keep the update pic coming.

[Posidon42]

Got to make some more good progress today. Finished up most of the wiring. Still not sure what that other connector is above, but I discovered where the clutch pedal wiring goes. Need to get with Greg as I am missing the harness that goes from the main wiring harness TO the clutch pedal assembly.

I was also able to reinstall the clutch as I realized that I forgot to install the thrust bearing. Oops... Hoping to have some time tomorrow to attempt to install the trans itself. However, because of what Greg said before, I hope that I don't have to mess with the k-member. I don't know if I have any sockets big enough for those bolts and I surely don't have the longer bolts he suggests I might need.

Oh, I found another pretty big difference in the wiring harnesses. The one connector that goes to the ECU is different. There is a difference in the molding one the internals of the connector that prevents it from plugging in. A couple of minutes with a small chisel fixed that. I took some good pictures of it and will post them later.

This is all good info that we didn't have before.

On my GXP there is a plug that just hangs near the brake booster. I'm wondering if that is the plug you are wondering where it goes. I've been meaning to get with CP about it, but have forgot about it until now.

I have also noticed that plug and wondered what it's for. At least I know something's not disconnected on mine now :)

[Greg@PacePerformance]

The correct oil pressure sensor is 12621234 - $35.00 if you don't want to cut the new harness.
I'll try and find the clutch jumper harness. Do you have a picture of the plug you have on the new harness

Edit: Found the pedal jumper harness. It is cheaper than just the pedal connecor. ;)

[BuildItYourSelf]

Looks like ill be needing some extra stuff also.

Any idea on the time it would take for you to get the parts in?

[Greg@PacePerformance]

GM has them so I'm looking at 4 days to me for the jumper harness.
We have the oil sensors in stock.

[Posidon42]

Already cut the oil pressure sensor. With the maggie installed, it was a total PITA just to get to the connector. I have no desire to try to get to that sensor. Greg, actually it would help me a lot if you could post the wiring connections between that pedal jumper sensor and the pedal connector. The pedal connector came with all white wires so I don't have a reference for connecting to the plug in the harness.

[Greg@PacePerformance]

Here are the images you asked for.
I'm not sure what else the clutch jumper harness plugs into just yet.

Image of body connectors. Unfortunately, I can't remember which is which but I am 90% sure the GXP connector is the one on the top in this pic.

The missing harness is what connects the X104 to the X110. However, since I can confirm the color codes are the same on the tri wire connector I am looking at, I am 99% sure that is what it goes to. Now I just have to correlate that to the harness I built and I should be good to go. Another forum member who is planning on doing this swap is going to stop by this weekend to help me out. It will be nice to have another set of hands, especially now that I am getting ready to move on to the hardware installation phase.

Almost going to be sad taking that trans out of the shipping crate :)

Oh, and Greg, I think I told you the wrong parts on that trans rebuild. I don't need the clutch apply pistons, I needed the pressure plates for the 3-5-R and 4-5-6. No biggie, as I probably won't have time to rebuild it in the near term anyway. I just want to get this car moving on its own power before I leave the country...

[Posidon42]

And here is another difference. One of the main harness connectors is wired in a different place in the GXP harness so it won't reach back to its original position. I ended up re-routing it and putting it by the ECU and it seems like it is a nice fit. And it gets rid of another harness that I have to look at when the hood is open.

The original connector was located at the top of the black bracket. The brass cylinder looking thing is for my line loc :D

Here is where the connector ended up, all snuggled next to the main ECU connectors.

I got the jumper harness in today. It is just a straight harness not like the GM picture shows a Y harness.
Connects from pedal to X110 connector.

[Posidon42]

Update - Tried to install my clutch today but it won't fit. I am 99% sure this is a Katech ZR1 kit for the Camaro but it is the kit that came with the donor Camaro transmission I bought. Waiting for confirmation from the seller, but the clutch housing is too tall to fit. So I ordered a Monster lvl 3 single disk for the GXP that hopefully should be in before next weekend.

[Greg@PacePerformance]

That clutch should fit just fine with the short ZR1 slave and no spacer behind the slave.
That monster is a good choice also, you will likly see more chatter than the Katech clutch though.

[Posidon42]

Let me know if you have some other diagnostic tips for this then. Also the ZR1 slave would need to be modified to fit and the input line was rotated clockwise by about 35 degrees so the line would have to be modified to fit anyway. Everything I can tell indicates this will bolt up but it won't disengage. And I actually think I will have less chatter as the katech unit had the aluminum flywheel and monster advised me to keep the steel one for that exact reason.

At least I can use the GXP slave and have one less 'one off' part in the system.

[Posidon42]

New monster clutch should be here tomorrow!

[Greg@PacePerformance]

Sorry I missed your response.
I modified my trans to fit the C6 slave as it is the same as the GXP only about 1/2 the price. The ZR1 slave is the same just shorter so it will fit.

I don't think the flywheel material determines chatter, but I can tell you that switching from an aluminum to a steel flywheel will take more throttle. It has a slightly different feel, but you won't have anything to compare it to so you'll be fine :)

The Monster should be a great clutch also. My level 4 does have a good amount of chatter so next time I will go back with a dual disc clutch.

[Posidon42]

Hrm... wonder what we are doing wrong then because when we tried to mate it up with the ZR1 slave, it looked like I was only going to get about 1/2" of spline engagement. The car is next door and I can take some pictures of it as we try to install it if it helps. How is the angle of the connections on the C6 slave as compared to the GXP slave? As I said earlier, the ZR1 slave has about 35 degrees more separation between the connections which would make it so I would have to take the pressure line to a shop to have it bent to fit.

Looking for some diagnostic information on the clutch alignment if you have it. This is my first time trying to install parts from another car and I am learning as I go...

[Posidon42]

Oh, and I will have to carve out a small section of the ZR1 slave to get it to fit on the GXP. There is a spacer on the Camaro which allows the slave to clear a 'notch' in the bottom of the trans cover.

BTY, how much and what type of MTL goes in this trans?

[Greg@PacePerformance]

Pics would be good if you have time. I curious.
To get the C6/ZR1 slave to fit the GXP trans you will need grind a slot in the case for the pressure line, grind the bottom of the slave to clear the fluid pump casting bump in the trans faceplate, and move the GXP slave's pressure line to the Corvette slave. Once you do all of that that the pressure line ends up in almost the exact position as stock. I even reused the mounting point.

You would not use that Camaro spacer at all.

MTL? Is that manual trans lube? If it isn't my brain isn't switched on yet.
The TR6060 takes 4 quarts of Dexron III ATF fluid.

[Posidon42]

Interesting. Didn't know the manual used ATF. Will try to take some pics tonight.

The sticker on the side of my trans case says Dexron III, Greg. I know that doesn't technically exist anymore, but I thought GM released a specific MTF for it rather than push manuals to the Dexron VI. I even read something somewhere that Tremec specifically did not recommend using Dexron VI. I was not aware that GM had cleared Dexron VI for use in manuals. Can you clarify, Greg?

FWIW, I still use Mobil 1 synthetic ATF, which meets/met the old Dexron III spec.

[Greg@PacePerformance]

I'll check it out. I used redline in mine ;)
