Filed Jul 20, 2020 · Transmission · 180,000 miles · MI

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 own a 2000 pontiac grand prix gt about 2yrs. Ago my transmission failed on me. My problem was diagnosed by a ase certified master mechanic. I wrote a letter to gm about this problem,which wasn't my only gm transmission I have had replaced within a 5 year time frame .I also had to replace one in a 1990 chevy cavalier z24 that was only about 9 years old at the time and I also had to replace the fuel injectors on that as well but that is a whole other story. I called dealerships to get the proper address of where I could send my letter of dissatisfaction with gm, and it was completely ignored!I didn't ask gm to pay for the whole transmission replacement,just to meet me half way and help a regular guy get to and from work with a dependable vehicle,take care of his family and not be hit with a 2200.00 bill that I am still paying on because I had to put it on a credit card and also get charged interest on top of that. Gm,ford and chrysler wonder why they are losing the battle to foreign cars? My personal opinion is this simple:they have higher tolerances when their vehicles are put together resulting in less mechanical failures. Don't get me wrong when I first entered the car buying market, I loved and only, bought american cars, but over the years my opinion has been swayed. I also feel that because my problem wasn't diagnosed by a mechanic who was employed by gm,that was just another reason my letter went unanswered.

I wanted to make you aware of a potential safety hazard on the road within gm vehicles. I already had two major transmission repairs on car with about 75,000 miles. The first problem occurred when my car was barely out of warranty, at approximately 42,000 miles. The transmission stopped shifting into overdrive. This forced us to drive 150 miles back home only going 40 MPH. This weekend, I experienced a total transmission failure. While driving on the freeway, my car suddenly made a loud noise and decelerated from 65 MPH to around 35 MPH immediately. The defect almost caused a major accident as we were in the high speed lane. When we got off the freeway and parked, we realized the car would no longer go in reverse. I shelled out almost $1,800 on a rebuilt transmission. My repair shop informed me that they are regularly doing rebuilds on the same gm transmission that is in my pontiac. A common sign on the failure is the loss of the reverse gear. In fact, parma transmission had done three alone during the week my car was in the shop. I am shocked that gm would install such a faulty and dangerous piece of machinery on its vehicles. I hardly find it coincidental that all of these owners are having the same problems with your cars. Please be sure not to group this problem just with pontiac. They put the same transmission in many of their cars, so you will need to figure out all the vehicles that are under this part number. I did not keep the old parts, but I am sure the shop I work with would be able to start saving all of the destroyed components that they continually repair.

2000 pontiac grand prix gtp has 42,000 miles. We purchased this vehicle new in january of 2000. No sign of transmission failure. Going from a stop loud clanking noise, car jerked 3 or 4 times. 5 minutes later after another stop sign the car did the same thing again. I stopped to a repair station, when I put the car in park it makes an awful grinding noise while idling. The service technician took the car for a drive and said to get it to a gm dealer because the transmission is going. I was told this should not have happened on a car that only has 42,000 miles on it. As I am looking through the consumer affairs complaint data base I am seeing 9 complaints that are quite similar. How many complaints does it take till this transmission problem is recalled? I paid $27,000.00 for my car 3 1/2 years ago and should not have to put $2,000.00 into it already. I purchase new cars simply because of feeling secure knowing that I take care of my cars with regular oil changes and maintenance and would not have to worry about any major repairs. I would like this resolved by gm repairing my vehicle at their expense.
