The truck started shifting hard. Had it towed home. Then towed to dealership. They diagnosed it with a faulty TCM #24256861. Then said it could be up to 18 months for the part. This is unacceptable in our opinion. Additional expenses, time missed from work, etc.
General Motors produces several years of vehicles with a faulty transmission control module (TCM). From 2008 thru 2015, Chevrolet and GMC 2,500 & 3,500 trucks with the 6.6 L Duramax engine and Allison 1,000 transmission all used the same TCM; part number 24256861. This part has experienced a very high failure rate. During the summer of 2022, the stock of replacement parts was exhausted and GM seems to be postponing the manufacture or new parts. An estimated 5,000 vehicles are currently unusable due to the failure of this part and no new parts available.

The contact owns a 2013 Chevrolet Silverado. After shifting into the park position, the vehicle stalled without warning. The vehicle was taken to a dealer. The technician stated that the vehicle was operating as designed. The manufacturer was notified of the failure. The failure mileage was 10,000.
On acceleration from a stop, the RPM's race while shifting. Vehicle acts as if the transmission is slipping from 1-2. early in the life of the vehicle I thought this was only something that happened the first time shifting after pulling out of the garage however, as the truck gets more miles on it, the problem happens more often and when taking off from stops when hot. Vehicle was brought to dealer to diagnose complaint and was told there was a bulletin to address this problem but since the tech couldn't verify it, they didn't do anything. Dealer said I have a good powertrain warranty so if something breaks later I should be covered. Not only is this unprofessional and poor customer service, they literally did nothing to attempt to diagnose or confirm the problem. There seems to be numerous complaints on this site related to RPM racing complaints.
When the vehicle's transmission was placed in park, it would roll on its own even with the parking brake firmly applied (our driveway is rather steep), as though the transmission was in neutral. We tried several times over the next couple of days to re-engage the transmission to work properly, however; nothing changed. We reported it immediately to the dealer the following Monday, but, their mechanic could find nothing wrong with the vehicle upon inspection.

Since I purchased this truck in June 2013, I've had several occasions where when the truck sits without being used for several days, when I back out of my driveway and put the transmission in drive, the transmissions slips. The truck won't move for a second, the engine RPM's race and then when the transmission catches, it will actually squeal the tires. Then at times it will continue to do this for the first several times I stop at a light or stop sign. This doesn't seem to happen once the truck has been driven for a distance, and it doesn't happen everytime the truck is used. I've talked to the service manager at the dealership and he says they've not had any issues with other trucks. I'm actually going to pick up the service manager and have him with me when I start my truck today after it has set for four days. I hope it does this with him in the vehicle so he can feel what's happening. I've been a loyal Chevy owner for over 30 years but I'm really disappointed in this truck which costs $45,000.
The contact owns a 2013 Chevrolet Silverado. The contact stated that while the vehicle was parked, the contact heard a loud clicking noise from the vehicle as vehicle rolled away and down a busy highway.

The vehicle was taken to a dealer and the mechanic stated that the parking haul was completely fractured and needed replacing. The manufacturer was aware of the failure. The failure mileage was 6,000. The current mileage was 9,100. The VIN was not provided.
Transmission down shifts multiple gears when I decelerate. The first occurrence happened at 70 mph causing a very hard deceleration and near loss of control of the truck. I have had three other like incidences at speeds between 45 and 70 mph. These happened on dry pavement and I was able to slow safely. Had this occurred on wet or snow covered roads, I have no doubt there would have been an accident. 2. at times when I accelerate there is no throttle response for several seconds. When the engine does respond, the truck accelerates as if I have the throttle floored. Again this has happened on dry pavement. Slick conditions would have caused a spin out. 3. vehicle surges between 20 and 45 mph. Engine RPM continually jumps 200-300 RPM causing constant surging. Besides being very annoying, it would be dangerous on icy roads.

The contact stated that while parked on an incline, the vehicle erroneously shifted out of park and into neutral, made a clucking noise and suddenly shifted into drive.

The failure mileage was 5,300 and the current mileage was 5,500.
