When are you guys changing your tranny fluid out. Dealer is recommending every 30,000. I have almost 50K on my 2009 G8GT. Please advise.

To answer your question, 50k for hard driving conditions, 100k for easy driving conditions. I am going to change every 50k.
My plan was to change it every 20k but seems like i am every 5k now due to other things lol.
Can't move out its own way- idk what number motor its on, how much boost, how big of a shot, its starts, im happy.
So we have anywhere from 20K to 100K... thanks for all the help :-) I did look in the manual, but I know there is a lot of "grey" in it. Many people have reported their cars being a quart low from the factory (or they just didn't notice it leaking - dim-wits didn't give us a dipstick, so I can't look at the fluid, smell it, etc, to gauge health. I do know two people that blew their tranny (around 20-30K miles). Yes, they both drag race the car (isn't that why we bought these), but this seemingly "monster" of a tranny found also in other aggressive rides has some potential to fall on its face. Now, I don't know if they were doing neutral drops or just plain stupid, but these guys know how to drive, and they drive hard. I just want to keep the 'environmentals' in the best shape possible.
My dealer wants to put in 13 qts, they do the usual "flush" (hopefully at the proper operating temperature) and they said every 30K. I guess since I have almost 50K on mine, I'm going to spend the $189 and do it (It takes them 1hr to do the job, it would take me at least three so its worth the $ to me). They said they replaced two G8GT trannies last month, both were covered, but they are $5K a piece! One guy at the dealership (who also owns a G8GT) said he does his every 30K. I don't believe after speaking with them, that they just want to up the frequency for the cash flow.
You also have TSBs regarding transmission slip (between 2 and 3), etc... I don't have any of that, but I understand that fluid can play a role in such behavior --- especially if you're a quart low.

I am doing mine at 25K. I look at the original trans/rear differential fluids like "breakin" types. Also, the trans on the V6 has two filters, both will be replaced. Old habits are hard to break. But I have to think that there are "impuries" caused by the initial wear, therefore the change out. A step further will be a complete brake fluid change out when new pads and rotors installed, hopefully around 30K. This will be the pre flight maintenance before the National Meet.

Thanks for all the feedback, I'm getting it done today. I'm located in Southern Dutchess County, NY but I use a dealer in NJ close to where I work (ez for drop-offs)... Plus I know a few of them there via common friends. If you're by Newburgh NY, there is a "modification" - friendly dealer there: http://www.colandreabuickpontiacgmc.com/What dealer/ where in NY are you?
