Pontiac Grand Prix harsh shifting problems

Filed Jan 19, 2016 · Steering, Transmission · OH

Steering: clicking noise when turning transmission has a light slip into 1st and sometimes hard shift into 2nd had this looked at in 2013 while it was still under warranty and the dealer didn't want to acknowledge there was a problem. This should be under recall since more people have this same problem.

Loud clunk when starting off. Vehicle did not shift into gears as normal. Transmission on this vehicle has been erratic for at least a year.

The initial issue that I noticed was when I was driving at 70mph at about 2000 rpms the rpms would jump up about 300 rpms when I would drive at a steady speed, just flat ground. It got worse and more frequent as a month went on, so I then brought to a gm dealership and they decided to do a transmission service (fluid and filter) and inspect what they could, everything "looked good". Now since then this issue has been resolved but the transmission slips and slams into gear, when I am in stop and go traffic or hitting a lot of stop lights, engine temp. Does seem to get a little high, even my mechanic thought so. When it slips it feels as if I hit a giant pothole and the engine/transmission is going to fall out. But this problem is so intermittent no one can pin point the problem, I have had three different mechanics look at this issue and one transmission shop. I have all of this and can't seem to resolve the issue, and not to forget to mention since I have owned the car since 2006, it has never shifted smoothly from first to second gear (when I accelerate from a stop light/sign). I like gm, but when this issue is all over the internet and gm hasn't done anything about it, I am starting to second guess my decision on vehicle manufacture.

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.

2006 pontiac grand prix gxp. Total transmission failure at 110k. This is a family vehicle which was purchased new. All service maintained, never even close to being abused and this transmission should be well within its life. As I have read, these transmissions are basically(supposedly) a beefed up version of the transmission used in the 3.8l models. It is same as used in the impala ss, where many many failures have occurred. Completely failed at 110k. Took into dealership on a monday, they ran diagnostics, test drive it twice could not find any issue. Vehicle towed in 24 hours later, with a complete trans. Failure. It started all of a sudden, would not shift properly, hard shifts, then would skip gears, then would not go into reverse, then would not engage at all. This is a very serious issue that deserves a recall. Only real option is to replace with a factory rebuilt transmission. Obviously gm will not do a voluntary recall, they are making too much on the sale of rebuilt transmissions.

Car transmission slips while taking off from a stop. It clunks and lurches forward unsafely. Vehicle transmission has been flushed and fluids changed. Seems to be getting worse. Does not matter if hot or cold. Does it 3 out of 5 times.

2007 pontiac grand prix gxp transmission failure at 96,000 miles (and 6 months out of warranty). Stopped at traffic light when I pressed the accelerator to go and heard a "clunk" and had no forward gears in automatic. Did have tapshift gears and reverse, though forward gears slipped. Took it to a local dealer (we were out of town) and told the transmission had failed. Had to have the transmission rebuilt at a cost of $3600. Plus car rental and hotel to drive home and return to pick up the car when it was repaired. Second gm transmission failure I've experience in less than two years with the previous one on a chevrolet trailblazer.

I have a 2007 pontiac grand prix gxp w/5.3l v8. Currently has 45,000 miles just recently started having issues with the transmission. From a dead stop trans will slip, than slam into gear, also shutters between 1-2, and sometimes from 3-4. Car does currently have powertrain warranty that I purchased with car. So car will be going in for repair under warranty (I hope) after reading online in a gm owner forum found out about the current investigation with gm transmission failures would really like to see a recall come of this. Because seems that this is a very common issue.. 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. Not to be mated to a 5.3l v8.

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!
