I own a 2017 Silverado 1500 ecoTech V6, 6L80 transmission, 91500 - over the weekend, I started having an issue shifting from 3rd to 4th. I noticed the transmission was over 190 degrees, as high as 230 degrees, then cooling back to 194. When attempting to shift from 3rd the 4th, it will start, then return to 3rd. It will do so 4 or 5 times until eventually skipping 4th and going to 5th. This happens when the transmission fluid is cold, 80s or when fluid gets to 190+. I called the local Chevy deal, who told me there weren't any open recalls for my VIN and that the diagnostics would be $190 which may or may not be a software update. They would not know until after the disanostics.

The six speed transmission 6L80 failed with less then 60k miles and before it's first service due at 72k miles, I have already had the transmission repaired so the original transmission components are not available for inspection. My transmission failed when I was driving across the Coronado bridge in San Diego CA. This bridge has no shoulders to safely pull over. I had my truck towed to Cummings Chevrolet in National City CA. and they confirmed the transmission needed replacing. Yes the check engine light did come on but it was already too late to save the transmission.

Not sure if it is a torque converter or the transmission there are no codes reading on the computer but multiple times when driving, I will lose all power in Drive and it will take a few minutes to catch up before it goes back in the drive and accelerates

While driving to work on interstate I22 in New Albany Mississippi I suddenly noticed serging and my RPM gauge fluctuating, I immediately knew it was torque converter failure at 134,000 mostly highway miles, which is a very low amount for a truck that I really don't work or pull trailers, I can accept transmission failure around 250,000 miles but not 134,000, upon research I discovered GM had a lot of issues with it's light duty truck transmission from this generation of truck due to substandard torque converter material.

I spent 40k cash for my 2017 high country to find out GM great idea of AFM and no good 10 speed transmission/torque converter was made with low quality and careless parts. I'm definitely getting me a lawyer to fix this [XXX] because all I've ever wanted was this body style but all they care about is money over quality. GM and they're retail sellers knew about AFW problems and sold us [XXX] anyway. They are saying that transmission issues aren't they're fault and actually getting away with that answer. Who's else fault could it be when it's the same problem with the same model. To be an American and get [XXX] by our own is getting old. If I can get sold [XXX] I can at least get a shovel with it...so I'm getting a damn good shovel/lawyer. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Shifting was noticeable with a hesitation. Dealership said it was normal. Developed into a shudder while driving. Shudder came up with transmission code and decreased power. Not driveable. Miles are less than 108k

I have a tork converter that locking the transmission and causing the truck to down shift and sometimes comes to a quick stop when braking. I am afraid if a family member drives the truck it could cause them to make a dangerous move in on goin traffic. Or not stopping and hitting a person or another vehicle. It hits hard and stops while pulling the vehicle in on coming traffic especially when not exspecting it all of a sudden.
