In drive, it acted like it wasn't shifting at all, like trying to start out in third gear on a manual, even though this has an automatic transmission. RPM's went up, and it gradually picked up speed, then seemed to drive fine, until I had to stop. As well, the engine is running a bit rough.
Next, I noticed that I had lost power to my windows, I checked the fuse box next to the glove compartment, the fuse was fine, and it had power. On top of this, my heater is also affected. I had it switched to defrost when whatever went wrong happened, and that is where it is stuck. I cannot switch it to any other setting, and I cannot turn the AC on at all, just heat. The rear defogger does not work anymore as well.
Lights, blinkers, etc seem to be working well though. I have read through some of the posts on here, but haven't seen anything of this scope. I did notice a hot wiring smell the day before this happened, when I got home I tried to locate the problem, to no avail. Anyone have an idea of what could control all of this? Any help would be appreciated.
I apologize for the problems you are experiencing. Were you planning on having the vehicle diagnosed? P Lease keep me posted.
Thank you,

I would be stepping hard on the gas but the rpms would remain low until I actually got it into third gear then it would cost just fine no problems. I thought it was the clutch that was causing all the problems because a little over a month and the car would not move anymore.
I just had a new clutch installed from a friend of mine who does great work and is a mechanic and I went to drive off and what do you know the car is moving again but the same thing. Lack of power it seems, stalls sometimes if I don't get the sync just right and you step on the gas hard you would think you would take off but low rpm's. The clutch also smells like it is burning.I am not sure what could be going on he said I may need to replace the flywheel. I do not want to go out and buy one if it is something else. I have been trying to find out more info on it but come up short. Any ideas?

This is only ONE of the service bulletins regarding the transmission on these vehicles, there are others.
GM is aware of this issue but isn't taking responsibility for it. I am personally not okay with that.

I apologize for your frustrations. Have you spoke with your dealer of choice? If not, I would recommend starting there. Please keep me updated.

I apologize for your frustrations. Have you spoke with GM Customer Assistance? Do you have this work done at a GM dealer? Please feel free to email me.

CHECK THE CATALYTIC CONVERTER. Mine was clogged and caused the engine and transmission to run rough, not shift well, not accelarate, all of the issues you are experiencing. Alot cheaper to replace a CAT than a tranny.
If you think you are experiencing concerns I would recommend speaking with the dealer and having the car checked out. Please keep me updated on your situation.

I had all the same problems that you are experiencing. The more I used the tap shift the worse the trans got.
This is not right!
Thank you for your post. We can look into the situation further (see if any recalls are associated to your nephew's vehicle specifically/help you work with a dealership towards resolving this concern). Please email us with your name/user name, contact information, the last 8 of your VIN, and your involved dealership.
Best,

The other day a guy in a 2005 Grand Prix pulled up next to me at a red light and asked how I liked my Grand Prix. I said it has a transmission problem and needs to be replaced. He replied "me too!".
Good Luck :shades:
UNTIL THIS TIME.
I own a 2008 GP GXP, and when I come to a stop sign and stop, then restart, the transmission is slow to go back into first gear. It hangs momentarily in neutral before slamming into low upon accelleration. Not real good for the transmission, and clearly leads to bigger problems. I would like to knnow specifically what controls these downshifts, and how to go about fixing it?
Also, I wish I had a dollar for all of you complaining about GM transmissions.
Safety organizations forcing recalls obviously think there is no danger in having your transmission malfunction in the middle of an intersection! Come on, GM! Where is your recall???!!!

I did not go to the GM dealer because of all of the previous times I did they usually made things worse. Once I took it in and got it back-the cruise control didn't work after that. Then the window had problems and they replaced the rubber around the bottom, had issues forever, took it back in and was told I needed a new window motor and it would cost over $500. I went home and ripped the rubber out, thing worked fine (till the button shorted out-replaced that and the window motor still works, hmmmm) Another time I took it in 3 times for an oil leak-paid every time and it still leaks today. Had the power steering pump replaced and now it is going bad again. -Those were all at the dealer. Now for some reason, I get to fill it up every few weeks with a FULL bottle of coolant. Fun stuff. I loved this car when I bought it. Guess I know why they stopped making Pontiac.
I'm sorry for the delay on our end. There may have been some confusion on our end as two of us are responding to the emails we receive from Edmunds. Have you heard from Christina at all? Again, I apologize for the confusion and want to make sure that you are assisted.

Yes, I have a 2006 GPGT showing 64k, no tranny problems, but it has had its share of ilks..5 batteries, 3 steering shafts, 3 sets of tires, and new engine mounts..Picked this car up in 2007 with 4k miles at 1/2 price. I really don't have any complaints, but the first sign of a tranny glitch it will have a new owner..
The 260 hp S/C V-6 is fun, and the sunroof is a Fla must have, runs on a diet of "Royal Purple oil", changed every 6k miles, tire rotation at same interval, rebalance if necessary.. The car is vibration-free at flat out top end..Brake are original, never touched..
Having owned 54 cars to date, this GPGT is okay, not great, and will remain in my garage for awhile longer..Having owned 74, 76, and 77 GPs with big block V-8, those were fun cars, and took the abuse well..
If GM replaces any trannies on the cars owned by posters on this forum, I would certainly like to know.. Best of Luck..Happy Motoring.. next car is a 5.0 GT Stang..
