- Hampstead, MD, USA

Transmission failed. As I was pulling a horse trailer the transmission went out of gear and left me on a curve in the roadway. No warring lights or any other kind of warning was given. I did take it to a dealer to have it checked out and was advised I would need a new transmission. The cost would be $7,000. I do not have the funds, therefore my truck is not drivable and is parked. I have learned this is a known problem with this transmission and GM is not doing anything about it. The very least they could do is pay for half of the repair cost.

Stalling with no power transmission is putting me at risk since I first purchased this vehicle. Transmission needs to be replaced because of the defective drive shaft on all 2017 models. Really serious problem with a hard shift and multiple misfire. Just not sure what to do at this point. I-??m still paying for a truck that-??s not working.

6L80 trans shudders and slips

- Elkwood , VA, USA

Transmission (6L80) torque converter failed at 76k miles. The transmission has never shifted well but was told that-??s how they shift. Vehicle is not used for towing. And all scheduled maintenance was followed. While driving down the road the transmission suddenly started shuttering and jerking. Luckily, I was able to make it to a transmission shop who confirmed the torque converter was shot. Called Chevy dealer and the service rep advised that there is a reason they have 30 of those transmissions on the shelf right now, it-??s a known issue. Unfortunately, it-??s outside the warranty. Transmission has already been replaced with a remanufactured 6L80. 500 miles after the new transmission installed, the torque converter went out again. Another 6L80 is scheduled to be put in. This transmission is unreliable and went out while driving down the highway. No warning lights ever came on to indicate any issues.

- Eltopia, WA, USA

2017 Silverado with 6L80, 59k miles - transmission failure due to TCC failure. Rough shifting, coming out of gear, shuttering when accelerating. Truck started to whine loudly when it was promptly taken to the dealership. Dealership dropped the pan and used magnet. Visible metal was in the transmission pan. There were no indicator lights on the dash from this issue. Requested goodwill warranty, gm replied they would cover 20% or $7k so I am stuck to pay $5k for a known issue. The replacement transmission is not new that they are offering, it is "certified refurbished" where they use the old casing with new internals. They are providing a 3yr/100k miles warranty on the new transmission. Deciding factors from GM were age, miles, service at dealership. Incredibly unsatisfied that GM is standing behind their vehicles not lasting 60k miles.

- Virginia Beach, VA, USA

While driving on the interstate the truck started jerking and vibrating, started slowing down, while in the fast lane, then a loud whining sound started, finally making over 3 lanes of traffic doing approximately 40mph got stopped on the shoulder. No warning lights or anything came on. Sat there not knowing what happened so I proceeded onto the freeway and it started lunging & squealing again, got off the next exit to find out it was probably the torque converter or transmission, so here I sit in Virginia & I live in Arizona stranded. And trying to figure out how to pay a $6000 to $8000 repair bill and to find out this is a common problem with GM transmissions

- Erie, PA, USA

while attempting to accelerate or decelerate we feel a hesitation and harsh shift. also along with the harsh shifting there is a shudder at speeds from around 50-72 miles per hour. yes it is available for inspection. it was a bit nerve racking not knowing if we should be driving or not, we bought the vehicle with 59,000 miles on it and felt some jerky shifting but didn't think anything about it because it was a chevy and that is all we drive, but now with the shudder we are concerned. we were on a road trip yesterday to help our niece move and she lives 3.5 hours away and we noticed the shudder again, ( we just had it in the shop for new tires, rims and balance thinking it was the tires and rims and alignment ) we were nervous to drive it back home, more severe shudder like driving on rumble strips and the steering wheel would even shake. no warning lamps or messages.

- Brainerd, MN, USA

I have replaced my transmission about 8 months ago-??$5200 and 15k miles later the transmission shudder is back. This is a safety issue because of transmission failure in traffic. There needs to be accountability from GM to fix this ongoing problem.
