NOT A DAMN THING. THEY WILL NOT STAND BEHIND THEIR PRODUCT! ESPECIALLY SINCE THEY DON'T EVEN MAKE PONTIAC ANY MORE. I WISH I HAD FOUND THIS SITE BEFORE I BOUGHT THE ONE WE HAVE.
The only thing I can tell you is if you have a transmission replaced - better do it through a GM certified shop like the dealer. My wife had a local mechanic replace her tranny with a Jasper tranny. We contacted customer relations for GM and tried to see if we could get some compensation but since a dealer service shop didn't do the work, no luck. The dealer cost to replace the tranny was practically the same as the shop my wife used. So check prices and be smart. The Jasper tranny comes with a 100,000 mile warranty btw. Good luck with it. I just gave you more help than I got from GM. lol pathetic car company.

Couldn't have said it better myself.
It's pretty sad when a transmission explodes at 47,000 miles with all required services documented (including trans flush and refill) and done by GM dealerships..........and they refuse to completely pay for it.
#471 of 487 My 2007 Grand Prix GXP is a piece of junk!
Feb 18, 2013 (6:14 pm)
When I purchased my 2007 Pontiac Grand Prix GXP it had 81,000 miles on it. This didn't worry me because I had 235,000 miles on my '04 GT and have never had a a bit of trouble with it. Besides it had a 100,000 mile warranty. At 97,000 miles the transmission went out. At the time I thought I was lucky because the warranty covered it. HOWEVER, now less than 10,000 miles later, it is going out again-and no warranty. A new one is $2800 plus labor. Really?! This is my third Grand Prix but now I see why they no longer make Pontiacs. I have always loved GM products but my experience with this car has changed my mind.

#474 of 487 2006 GXP Transmission
Feb 19, 2013 (2:52 pm)
My wife's 2006 GXP just had the tranny replaced by the dealer. They opened it up and found the third gear pack had been burned up. We got 146,000. miles out of the original tranny. I had bought an extended warranty from a company knowing the trans was going. But the Warranty Company said since I did not do the 50,000. miles fluid change they would not cover it. Pontiac Warranty Service book says 100,000. miles for normal driving. I did it at 88,000. So a fight is coming which I hopefully will win. I opted for a new trans not a rebuild. A little more money but it came with a 3 year 100,000. mile warranty. Worth it. The car runs great and is smooth as hell. First long trip got 24.5 mpg. I still wish Pontiac would wake up and start backing the transmission.

Is your extended warranty one of our GMPP plans?

#476 of 487 Tranny Slipping
Apr 02, 2013 (11:42 am)
Hey everyone, having an issue with my '03 GP GT 3800, ~280,000k (don't judge). The tranny feels like it's slipping. If I take off too quickly from a stop, of if I punch it on the highway to pass, it just overrevs to the point that if I don't let off the gas and let it calm down, I can't re-engage the gears. This only just started last week. Now, before this, I was having the hard shift issue, which I've just been blaming on my bad O2 sensors sending out a misread. Could this slipping issue be associated with that as well, or am I way off track? I'm looking to get a new car this fall, but I'm worried this car won't hold out that long.. Any suggestions? Thanks!
#477 of 487 Transmission Needs Replacing
May 07, 2013 (2:28 pm)
2007 GXP that I bought new. I appear to have the same transmission problem that most people are reporting. 109,000 miles, but it's been acting up for a while. No codes when checked in the past. $2800 plus tax to replace the transmission. I've emailed gmsocialmedia.com to see if there is any assistance they can provide to help to reduce the cost. The car had a 100,000/5 Year warranty and of course this doesn't happen till after the warranty expires. I'll post any updates and response that I receive.

Sounds like a duplicate of my 2007 GXP that I also bought new....but mine only made it to 47,000 miles before the TCC exploded and destroyed the transmission.
Like you, mine went just after the 5 year/100,000 mile warranty expired...even though I didn't even make it halfway on the 100,000 mile part.
I had the transmission checked and flushed just a few months prior to the destruction and while it was still under warranty. All service including every oil change was done by the GM dealership since I owned the car.
GM still made me pay them $1000 for a replacement transmission even though there are close to 400 "known" instances of GXP trannies exploding like this.
Good luck with GM social media though....they were completely useless in my case. The only reason that I was able to get any help from GM was through the Service Manager at my dealership. (Amusingly the GM social media people were so out of the loop that the guy from their office that kept calling me and getting absolutely nothing accomplished.....didn't even know that the service manager had already made arrangements.)
Good Luck however.....and remember to report GM at
