OK. so as you may already know i have one fucked up transmission and after my standing mile adventures it's only gotten worse. Anyway i spoke with RPM Transmission about having them rebuild my tranny. They told me they could do a clutch upgrade + fix my transmission (as long is there's no real serious damage), including my gears slippage problem. This seems to be cheaper than what it would cost to fix the tranny at any local place alone.


Anyone have and thoughts on this, or on RPM Transmission, i don't have any personnal experience with them but i heard a few good comments.

I am assuming this is not Warranty "able".

They've already "voided" his warranty.

I believe Fran (Race Proven Motorsports) puts RPM's trans in most if not all of the cars they build. You could pm him and ask him on LS1tech Frans96ss.

RPM has a few Vettes running around that make high HP and the trannys they built are holding up.

LIVERNOIS modded a Vette with an A6 that makes over 800hp that's street driven.

Also I believe Century Trans has an upgrade ready for our trans.

Mike @ New Era suggested RPM for my trans as well. He is likely going to have them rebuild his tranny for his 2010 Camaro.

I'm interested in this as well, I'm having a 1-2 shift problem and my car has been sitting at the dealer for two weeks waiting on a GM rep, go figure.

Same here as I've asked. They were also a Indy HP street car shoot out sponsor.

The priceis not to shabby sounds tempting. Sounds like he will have alot of work coming his way with all the trans problems everyone is having.

You are shipping yours for the upgrades or are they doing a core exchange?

Shipping to fix and upgrade, They don't do core exchange, anyone know if replacing all those clutches will do anything? One I thing I found intresting is how much emphisis he put on having a proper professional tune, said it was just as important as upgrading a tranny.

We are currently developing our 6L80 program, so nothing set in stone yet. They will be offered in 2 stages. We are custom making our clutch packs on our CNC machines to increase capacity in the weak areas. More details to come...

And as RPM mentioned, tuning is very important on these units.
