I had a 2019 Sierra (same platform as the 2024 Silverado, it uses the GM "T1" platform, and I also experienced a TCM failure on the truck at 50,000km (about 35k miles). It failed after I parked the truck in a parkade, and I had to push my truck all the way outside of the parkade for the tow truck to be able to load it up. That was a pain! Trucks with under 100,000k should not be experiencing TCM failures.
GM then refused to give me a free loaner vehicle because they "had to figure out if the TCM would be covered under warranty". A week later when the truck is fixed, obviously it was covered under warranty, but they never did give me a free loaner. All this happened in the middle.of a snowstorm too.
I now drive a slightly older Ram, a 2017, and it has been flawless during the time I've had it.
To be fair to GM though,.my dad has a 2024 Silverado with the 3.0 diesel and he absolutely loves it. The 3.0 diesel.is a great motor with the 10 speed. It is a really nice truck.
The TCM failure I experienced was with the 8 speed (5.3L and 8 speed was a common combo in 2019 and the 10 speed was only available on the top trims). it would be nice to know if these failures mentioned in the article occurred on the 8 or 10 speeds, I think GM still offers the 8 speed on their base model trucks don't they? Or have they fully dropped it now for the 10 speed?
