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.

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.

Tl*the contact owns a 2006 pontiac grand prix. The contact was driving approximately 15 MPH on normal road conditions; proceeding to make a turn. The steering wheel began to make a loud whining noise with a loss of power steering. The speed rate was increased and the vehicle resumed to normal operation. There was also a reduction in the whining noise. The failures occurred whenever traveling at a low speed rate. The vehicle was taken to an independent mechanic for inspection. The mechanic dispensed an unknown solution in the vehicle. The failures continued with no resolution. The failure mileage was 18,000.

Power steering pump is losing fluid,this has happened twice now. Car was taken into dealer and no leaks,or fluid was found under car. All they would do is fill up pump with more fluid.the fluid must be going somewhere? My car makes a very high whining sound when it gets low on fluid. I was told this is a valve problem in pump by other people.

I started my 2004 pontiac grand prix gtp one very cold morning and noticed a whining noise from under the hood. I purchased this vehicle used in 2005 with about 16,000 miles on it. Once the car warmed up, the whining noise went away until I drove it. I heard the noise again when the transmission shifted from first gear. At that time, the mileage was about 74,800. About one 3 days later, I took it to a local lube shop to have the transmission fluid changed. After the fluid was changed, I did not hear the whining sound again until about 2 days later on my way home for a lunch break. The next morning, I heard the whining when I started the car to warm it up. After the car warmed for a while, it hesitated to move when I put it into reverse to go to work. It also hesitated to move when I put it into drive. The mileage, at that point, was about 75,000 miles. I brought it back home and called a local repair shop who ended up looking at it and said the trans was shot. I then called gm about to express my dissatisfaction and to ask for some type of assistance. They referred me to a dealer for a diagnosis. I took it to sullivan pontiac and was told that it was a possible problem with the valve seal. The estimated cost to repair would be 2,600. Considering I do not drive my car under heavy conditions and the recommended trans service is due at 100k for those driving conditions, I do not think this problem should be occurring at this mileage.

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.

1998 grand prix with about 59000 miles. Power steering to the left seemed to be cutting out periodically about a week before all power steering to the left failed. Very difficult to turn left at low speeds. Fine turning to the right, but very difficult to turn left, must use a lot of muscle. Also makes a grinding or whining noise when turned all the way left. Steering failed all of the sudden. Nearly had an accident. Luckily going slow enough to stop without getting hit. Very difficult to steer left.

Transmission started making a whining noise and at times would shift hard and sudden. Took to trans. Shop, was told pontiac had put out a bulletin stating a problem with the trans. And what was wrong if a certain code came up.it turns out they have been having trouble with the pressure sensors on the trans.,and need to be replaced.this ended up costing 500.00. I called the pontiac dealer and was told it was something they were having trouble with but there was no recall.

Transmission sometimes will start to make a loud whining noise and start to shift hard and sudden. Doesn't do it all the time,usually after I have been driving a while. Also sometimes feels like it is surging. I heard the 3800 transmissions were a good transmission, I don't know.
