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.

The car was about to enter the mass pike when all forward motion stopped. The transmission was in 'drive' but it acted as though it had slipped into neutral. The car was dead in the middle of the road and there were a number a near miss collisions before the emergency vehicle arrived. The car is now at a gm dealership awaiting a transmission rebuild. We bought this car new and have had a number of transmission issues starting at 12,456 miles. Within the first year of ownership we reported a 'clunking' noise to the dealership - they said they could not recreate the problem. We had additional issues where the car would 1) not move when starting from a traffic light or 2) would act as though it was in neutral when coasting and then 'bang' into gear several seconds after stepping on the gas pedal. These issues were reported to the dealer at 33657, 45381, 51284, 56446, 61543 and 72552 miles. In each case, except for the one at 56446 miles the dealer said they could not replicate the issue - but they charged for the time. At 56446 miles we tried another dealership and they spent over an hour testing the car. Finally, they did experience the problem. They replaced several transmission parts but we experienced a shuddering problem less than a year later. They detected a possible torque converter problem at that point but said it the could be driven and no other parts of the transmission would be affected. There is a common issue with the transmission in gm v8 cars - there are many reports of failures and expensive repairs. It appears to be a design issue. The symptoms started early on, and despite our multiple reports of problems and exact adherence to the maintenance schedule there was almost a serious accident.

Transmission slips or shutters from a stop, then slams into gear. Shift from 1st to 2nd is slow. Shifting manually works ok. This is a common problem with the gm 5.4l engine 4t65e-hd combination and has been happening nearly every time I drive the car. Local transmission dealer says he sees this all the time and is a known issue. This has been happening for quite some time, but because it started after the warranty expired the deal would not do anything.

Transmission is slipping for several seconds, then catching with a sudden "thunk". Apparently this is a common problem for gm cars (pontiac grand prix gxp, chevy impala ss & chevy monte carlo ss) equipped with an ls4 engine and transmission. This is a dangerous situation as it comes and goes without warning. Sometimes everything is fine, but if you are pulling out into traffic and the problem occurs without warning you may not be able to accelerate appropriately and result in a crash.

1. Events leading up to failure = regular day-to-day vehicle use. 2. Failure = transmission, when accelerating from a stop, transmission seems to slip and then slam into gear. Also, occasional hard slam into 2nd hear under part throttle. 3. What was done to correct failure = repair shop inspection with pan removed 1-year ago, nothing found. Problem still exists..

I have a 2005 pontiac grand prix sometimes when I press on the pedal the car hesitates. There is also a whining noise coming from under the car. At first I thought it needed a tune up so I had the spark plugs changed. I thought this would correct the problem, but the car continues to stall. Just the other day I was driving and the car would not go. It felt like the transmission was slipping. So I took it the shop and they said I have a problem with my transmission which I already knew that. I have talked to other people with this same car and they have also had transmission problems. I would like to know if pontiac is aware of this or did I get a bad car.
