2024 Suburban bought brand new. Service Transmission Warning lights up. Been to the dealership shop about this 4 times now. They replaced the TCM with kit, seals, & tranmission fluid. Problem occurred again 200 miles later. Dealership just stringing us along without actually fixing it!
Pulling off from a stop sign on a hill, the car wouldn't accelerate and rolled back hitting a pedestrian and then jerked forward aggressively burning rubber on the tires. I smell the transmission burning. Luckily the lady didn't want to press charges.

transmission failed causing to replace do to the system on CHEVY motor changing from 8 cylinder to 4 cylinder and a thermostat on a transmission line.
The transmission was acting weird and felt like it was revving up and down while going 20-30 mph. After turning into my neighborhood there was a loud clunck like some dropped off the truck and it completely fell out of gear and just rolled to a stop. Shifted it into park, turned the truck off and back on and put it back in drive it went into gear and allowed me to drive to my house but still acted like it was about to drop out of gear completely again. My neighbor has a 2015 Silverado and 2017 Tahoe and both transmissions did the same thing and had to be replaced, all between 100-125k miles.
