My 10L1000 transmission had a catastrophic failure internally which caused it to rough shift, sudden down shifting, not want to shift into gear at all, and high engine rpm prior to roughly shifting. I took it to the Chevy dealers mechanic the very next business day, only to find out that from the mechanic that this is a common occurrence with Chevy transmissions in my truck and google also verified this to be a common problem. The mechanic from the Chevy dealership also stated that there was larger metal chunks than normal. My truck is available for inspection asap. The manufacturer and vin lookup contradicts the mechanic and google stating no issues or recalls for my transmission. After speaking with the manufacturer, I became highly concerned due to their unwillingness to address the obvious issues known by so many. If I wasn’t such a safe driver and immediately brought it to the mechanic, this could have caused a terrible accident leading to extreme bodily harm or death even. According to a quick google search of the 2021 Chevy 2500 transmission problems and my mechanic this is a well known problem even though Chevy manufacturers refuse to acknowledge the issue or implement a recall. There was zero warning lights or lamps to indicate this problem. I am extremely concerned with the manufacturer’s response to my concerns and their unwillingness to correct this issue before it cost someone their life. This catastrophic failure with the transmission having metal shavings throughout it and extreme damage to the transmission valve body and being well known and reported by many other customers has to be addressed. Chevy’s unwillingness to acknowledge people’s claims in this has left me with around $10,000 in monetary damages and could have lead to bodily harm or death if I would have been traveling on a main highway or interstate when it occurred. At the very least Chevy needs to be held responsible for this known and reported issue before it causes death or injury.
