2010 Chevrolet Silverado 1500 Transmission and drivetrain Problems

“My husband and I were driving about 45 MPH down a steep hill, towing a utility trailer, on sr87 in the mountains when the door locks clicked and the engine turned completely off with no warning. The steering wheel locked up and the brakes did not work. My husband put the car in neutral as it accelerated down a cliff and attempted to restart it with no luck. There were no cars immediately around us so we were able to coast to a stop on a steep incline. When we got out to check it, there was oil all over the wheel wells and still no warning lights had come on. …”

“Heard a ticking noise coming from under hood of vehicle while pulling away from fast food establishment. Pulled over to find that transmission dipstick tube had fractured. Went home and found that GM had issued a customer care bulletin back in 2012 about this issue. However, I received no letter about this problem. I contacted GM this morning and they refuse to fix the problem under this bulliten . This should not be a bulletin , but should be a recall since it involves potential problems with the transmission. …”

“This has happened twice in the last week. Today I was sitting at a stoplight with my foot on the brake and suddenly without warning my 2010 silverado accelerated and lunged forward about 3 feet. Fortunately there was not a car or person in front of me or I surely would have had an accident then the engine started missing. At the same time my check engine light came on. Service traction control, service stabiltrak, engine power reduced flashed on my dash. I limped home at 10-15 MPH max! After about an hour I started it and it ran just fine both times . …”

“I purchased this vehicle at a somewhat reliable local dealership only to have the vehicle in and out of the shop a total of 6 months for the first year and a half of my ownership. The problem with the vehicle has been, and still is, the transmission and it's ability to slip in and out of gear at random. At intersections, stops and starts, as well as in movement the transmission will disengage and slam into gear with a loud clunking noise and jerking action. On an incline, it will actually roll backwards thus forcing the need to constantly cover the brake for this concern. …”

“Transmission makes clunking noises when shifting at 25,33 &46 MPH. Sometimes there is a very loud clunk from the transmission. This has been occurring ever since we had 24000 miles on the vehicle. Current miles 59000mi. Gm dealerships could not verify the noises. One dealer changed the TCM and torque converter. Very same noises within the same week of the change. Still happening.”
