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.
According to GM 2009 to 2015 Chevy Silverado transmission control module and wiring harness failed. People have been without their cars for more than a year ours has been down for 6 months. NO dates for the parts to be back in stock.
The contact owns a 2013 Chevrolet Silverado. After the ignition key was turned to the on position, the vehicle failed to start without warning. The vehicle was taken to a dealer where it was diagnosed that the air intake hose needed to be tightened. The vehicle was repaired, but the failure occurred several times. The service engine warning light illuminated. The vehicle was taken back to the dealer where it was diagnosed that the fuel sensor needed to be reset. On another occasion, the cam shaft position sensor needed to be replaced. The vehicle was repaired both times. The manufacturer was notified of the failure. The failure mileage was 33,000.
On the way to work on Monday morning, Sept 1st, 2014 as my husband approached a stop light he noticed the vehicle at the light backup lights come on. He thought they may have pulled too far up under the stop light and were just going to back up a little bit so he applied his brakes. The driver of the other vehicle proceeded to push the gas and slam in to the front of my husband's truck then drive off. My husband proceeded to the nearby Pilot fuel stop looked around to see if the other vehicle was there then called the police to file a report. After that he went on to work a few miles down the road. Worked his shift, stopped and put a little gas in his truck and drove the 9 miles home. Parked in the drive went in the house and came back out a few minutes later there was smoke then fire coming from around the front tire of the truck. It soon became engulfed in flames despite the efforts of the local fire department. The truck was a total loss.

I was traveling at 55 miles per hour on a 2 lane highway. Vehicle became unresponsive to steering and brakes were not working correctly. Peddle had to be pushed all the way to the floor. Got vehicle slowed down and turned off. Once restarting steering was very tight but functional. Similar incident in 2013 resulted in an accident. Several more steering issues since December of 2013. Has been taken in for service and nothing has ever been fixed.
The vehicle's engine compartment caught on fire following going through a car wash. I stopped after pulling across the street and noticed false fault indications on the display, followed by smoke blowing from the heater vents. I pulled into a parking space, raised the hood, and saw flames coming from the left rear of the engine compartment as you face the vehicle. I borrowed a fire extinguisher from a store and put the fire out. I have received little information from GM in 2 1/2 months and nothing indicates to me they have taken this engine compartment fire seriously. Had this occurred at speed, in traffic, etc. It would have created a very dangerous situation not only for myself but others in the area.
