2006 Pontiac G6: transmission slipping

Filed Feb 28, 2019 · 90,000 miles · NH

This is a 2006 pontiac g6 with the 3.5l lx9 v6 engine. At 90,000 miles I am having transmission problems (automatic). The transmission slips in 2nd and 3rd gear. The car reverses normally. All maintenance is done by myself or the dealer. I changed the transmission fluid with genuine gm parts and fluid. I noticed the fluid was slightly discolored and very tiny pieces of metal were in the pan. The transmission still slipped in 2nd and 3rd gear after changing the fluid. Obviously I want to avoid putting in a brand new transmission. I want to check the computer and and any electrical pieces that correspond with the transmission first before I decide. As a side note,I did bring the vehicle to gm for a diagnosis and apparently there was a code for a transmission position sensor. However I attempted to start the vehicle in drive on many occasions and the vehicle would not start which is what that sensor is suppose to do so I know it isn't the sensor.

The transmission slips severely between 1st and 2nd gear. When I am at a stop and push the gas to go the car has trouble shifting. Usually the speed is between 0-15 MPH. I have stopped pulling out in front of any car because there isn't enough speed to go fast enough and it's going to cause a wreck. I have had this car looked at by a transmission mechanic and was told there isn't anything showing as wrong, I have taken it into a dealer and again they couldn't find anything wrong but suspected an issue to be module or solenoid that would cost over $1500 to fix and they couldn't guarantee it is the issue. Both mechanics drove the car, could feel the issue but couldn't figure out what was causing it. This is ridiculous there is an horrible issue with the car and no one can pin point what the issue is. And now the seat warmer on the drivers side keeps turning on by itself.

My pontiac g6 was running perfectly fine with no lights or warning signs and always well maintained to date. I pulled up to a red light and the light turned green and my car would not move in drive it would only rev. I was able to put it in trip tronic shift and make it to a transmission shop. It was slipping also in trip tronic in first and second. The repair places said that it was internal transmission problems. My only option was to get a whole new transmission put in well a rebuilt one. This should not be happening to a 6 year old car that was well maintained with no warning signs. I talked to several people at gm headquarters and they just don't care and act like its my fault there bankrupt pontiac company produced unworthy reliable cars. And dixie gm where I took it to get fixed wants to rip me off and charged me double of what other transmission places in the area quoted me. I took it there because I thought they would be honest and give upfront answer and not jack me around because im a young women. Its not as if I went to mcdonalds and asked for a steak. Come on gm I thought you guys were better than this!!

Purchased a 2006 pontiac g6 gtp, I have recently caused many close calls of harming peoples life due to the failure of shifting of my transmission in a fairly new vehicle. The transmission slips and does not go into gear sometimes and when entering the highway everyday is a challenge if I will make it or not. The vehicle decides if it will go or not and I don't believe this 2006 vehicle should be on the road or others to be sold until this ongoing problem across the nation to be solved. It happens at 65,000 miles on all vehicles that have reported this issue.

My friend's 2006 pontiac g6 4-cylinder transmission is slipping gears and a hard 'thug' is heard while he was driving his vehicle. He has told me that this has happened to his car for a couple of months now and he has 83,000 miles on the vehicle. I researched the transmission problems on google and he is not the only one that has had this problem. The link is below for the website.
