Transmission failure at 180k miles. Car will not shift on it own I have to force car into gear by speeding up hearing transmission whine and then letting off the gas pedal so transmission shifts gears. This is on all road conditions. So many complaints have been made why has gm not issued a recall on this matter.

I've had to replace the transmission at 67k miles, and it went out on me again at 110k miles. I replaced the transmission at not only a gm certified dealership, but a pontaic dealership (john hine pontaic) in san diego. The transmission was a gm certified refurbish from canada. No recalls from gm, and no reimbursement policy. This is an issue.

Soon after purchase, transmission slips gears coming out of a stop. August 2013, transmission dropped out, driving 30mph. Car was not drivable; no gears. Transmission was replaced. Now one year later, slips gears at 40mph. Headlights went out while driving in the dark. Use of turn signals causes high beams to activate. The cabin fan (A/C and heat) never shuts off. Heat works intermittently. Car seems to shake at times. Feels like a flat tire but when checked, tires are fine. Car rolls when in park, even on flat surface. Car rolls back when in drive, even on slight inclines. Never certain of brakes; at times, works as normal, other times, pedal must be pushed close to the floor to activate brakes.

I am adding my transmission failure to this data base. This is a one owner car and driven with care. The transmission failed at appromimately 5 years and at 55,045 miles . This cost $4,343 to replace with a srta transmission so I could get home from vacation. Why is nothing being done about the numerous transmission failure complaints? My car now has 80k miles and I feel as if I am close to losing the transmission again. I have the invoice to back up this claim.

When driving the 2008 grand prix gxp (5.3 with a 4sp automatic overdrive) at low speed the car started shuttering and slipping in gear. Made it home slowly and pulled over and checked to ensure transmission fluid full. Call dealer to file warranty claim and tried to drive to dealer and car went 1/4 mile at 10-15 MPH and car transmission went completely out. No gears in reverse, drive or manual mode. Car had to be towed to dealer. This is a daily commuter car to work and home and I am working this week and has left me stranded during the holidays. No rentals available due to holidays. Complete transmission failure from a 2008 model with less than 100,000 and I put 12,000 on it since april when I bought it with 82,xxx.

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.
