2005 Pontiac Grand Prix: complete transmission failure

Filed Nov 3, 2013 · Transmission · 79,000 miles · OH

I bought this car from an older man who rarely drove this grand prix kept it in great shape after a year when I bought it I noticed the transmission would go up to 212 degrees and it would shift very hard out of first and out of second then it started doing it at 180 degrees I took it to a gm dealer to get a transmission flush and they said I would be doing more harm then good because of all the broken down gears in the transmission. It slips a lot now and they want me to buy a new transmission after a year of owning it when their was absolutely nothing wrong with it when I purchased the car.

My 2005 pontiac grand prix gxp transmission just stopped while I was driving. I have read how about 225 people have documented on a website of their transmission issues with this same make and model vehicle here http://www.gmls4.com/index.php/topic,33.0.html with my car only having around 80,000 miles and has not been driven hard I am really disappointed in gm for making a vehicle like this. The transmission is now whining and I can drive it about ten yards and there will be lose of power and it will not drive in any gear on the vehicle. I am very disappointed and need this corrected and will ultimately need a new transmission which will ultimately have the same problem down the road.

I have a 2005 pontiac grand prix gxp with recurring transmission trouble. The transmission has been replaced by gm at 50% cost and the same symptoms are occurring again. Failure is eminent. I have what most are calling the rev and clunk syndrome in my current transmission. My 50,000 mile warranty on the new transmission has just ran out, but I have records where complaints were filed with the dealer with nothing found. After doing some research I see that I am one of hundreds that have had this same problem. Help!

Transmission showing signs of failure despite using the best synthetic tranny oil and regular tranny oil changes. The car has only 117 000 kms and slams into gear after a slow start. Also shudders sometimes before a gear locks in. Apparently these are common problems that occur just before complete transmission failure.

Transmission on my 2005 pontiac grand prix gxp failed on 11/23/09 at 94,622 miles. Car was brought to dave sinclair buick/pontiac/gmc and the transmission was replaced under warranty. The second transmission started bucking while going up hills at 120,000 miles. Took the car in at 120,703 to the same dealership. They said no problem was found with the transmission and it was in good condition. The transmission failed again at 124190 with less than 30,000 miles on it. Dave sinclair replaced the transmission for $2979.19. I have complained to gm district managers about this not being an isolated incident with these transmissions and that I should not be responsible for this replacement. There is an issue with the 4t65e-hd transmissions where there is not enough line pressure getting to the transmission due to a faulty transmission pan magnet under technical service bulletin number 08-07-30-040b from may 2009. Since my transmission was replaced well after that, my transmission should not have failed as the symptoms were exactly the same as what should happen with this issue. Furthermore, this new transmission is doing all the same things the old one started to do before it died. Gm has denied my reimbursement claim 2 times and I have not stopped complaining. I am about to drop off my car for the third time in less than a month because dave sinclair has not resolved the issues with this new transmission. Gm should recall this transmission and reimburse all people that have paid for replacements.

My car at only 54k miles, transmission failed, causing to loose power in traffic. I had the transmission rebuilt ($2400), 8 months later it failed again ($1200), 2 months later, failed again ($0-warranty). Mechanic finally figured out it was some pressure relieve valve on the transmission, causing pressure to build up, causing the torque converter to explode, sending debris throughout the transmission. I did not go to dealer as car for that model year was out of warranty, but went to transmission shop who has been in business for about 30 years. I wrote to gm, but got no monetary satisfaction. Many people I've read about online with this type of transmission have had similar problems. I've never had transmission trouble in all the cars I've ever owned. It would seem there is a defect in this model, and would like to recoup the money spent on this issue. It seems it's on gm models with a v8 front wheel drive transmission. Like the pontiac grand prix gxp, and monte carlo ss, buick lucerne v8.

I own a 2005 grand prix gxp ls4 v8 with 60kmi. The transmission has shuddered on the 1-2 shift and sometimes delayed on the 2-3 shift since 40kmi. Every time I have taken the car in out of warranty, and even while it was in warranty, the problem could not be replicated. I know the 4t65e-hd transmission in this car is subject to failure as I am a member of many online forums that have cars with the ls4 v8 and 4t65e-hd and the transmission failure is the number one topic of discussion. It will leave you stranded without warning, and may break in the middle of traffic causing a dangerous situation to be in. It seems to be too much for a transmission that was designed to be mated to a v6 engine to be mated to a 5..3l v8.
