- 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.

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.

After a full service of the truck in July 2022 with approximately 90,000 miles (including oil change, tire rotation, transfer case fluid exchange, front and rear differential service, coolant system flush and refill, front and rear brake pads and resurface of rotors, and transmission fluid flush and refill), the truck began jerking and stuttering (like rolling over rumble strips) in October 2022. In February 2023, the truck was taken back to dealer service department for an oil change and inspection of the jerking/stuttering issue, the service department replaced the spark plugs, inspected the wires and connectors, and performed a throttle body service with the expectation that this would fix the jerking/stuttering issue. It did not. In May 2023, the truck was diagnosed with a transmission issue by an independent service center and confirmed by the dealer service department. From the start of the issue in October 2022 until diagnosis of the transmission issue, no warning lamps or messages ever appeared. The dealer service department stated that the torque converter is bad and that it would be best to replace the full transmission. The truck is still drivable, but the dealer service department suggested that it should not be driven as the transmission could fail completely at any time. At this time, safety is of utmost concern and the truck will not be driven until fixed as we do not want to put ourselves, our passengers, other drivers, and pedestrians in an unsafe situation if the transmission fails.
