My transmission is slipping and causing safety concerns while driving on the highway. It’s a 2017 Chevy Tahoe that has less than 100,000 miles and we have been reading on the internet about many others having the same problem. We just took it to a shop and they informed us that it’s a common issue with this model chevy and it will cost $5,000 to replace the transmission.

All of a sudden my transmission (6 speed) started slipping. No abuse /drag racing lol. Just normal driving. I limped into my local dealer and they said the transmission was “shot” and that they couldn’t let m drive it home. Also the transmission mechanic was outside smoking and I vape so I started a conversation with him about these 6 sp transmissions and he said “ I can’t count how many I’ve replaced” “ even with less than 80k miles. This is negligent at the least by Chevrolet to intstall dangerous and threatening transmissions. Bad Chevy BAD!

The transmission went out at 93,000 miles and we took it in to be repaired under warranty. We were told a new transmission would be installed after being shipped from Detroit MI. When we picked up the vehice we discovered it was not a new transmission but a remanufactured transmission. We drove it home 25 miles home and it did not shift properly. We immediately called the dealership back to report it and was asked to bring it back. The dealership check it and said there was nothing wrong with it we just needed to drive it so it could learn our driving habits. This transmission lasted 104 days. We were out of town and my husband drove it to town to get breakfast and the transmission was slipping so bad he almost didn't get back with it. We had to have it towed to the nearest dealer 30 miles away and rent a car to get home. The second remanufactured transmission was installed by GM on 5/23/23 and we picked it up on 5/26/23. Upon driving it home this 2nd transmission was shifting hard. I contacted GM regarding it and was told to take it to be checked out. Once again we were told we just needed to drive it so it cold learn our driving habits. It is unsafe to drive as my husband drove it 4 miles to the grocery store and still at the traffic light he is pressing the gas to go and the vehicle would not move/go forward. He quickly had to put his flasher on and put the vehicle in park to keep from being hit from behind. He was finally able to get the vehicle to move and got home. The vehicle shifts so hard that it feels like you have been hit from behind by another car. GM keeps telling me there is nothing wrong with the vehicle but it is not safe to drive when you dont know if the transmission is gonna go out while you are going 70 mph down the interstate or get rearended becasue yourr vehicle doesn't move when the light turns green.
