2016 Chevrolet Suburban transmission problems

Filed Aug 19, 2026 · Transmission · TX

The transmission failed suddenly and without warning. When I Went to pull out from a stop sign with cross traffic doing 55 mph, the vehicle shuddered and stopped pulling. We barely had enough momentum to get out of the way of oncoming traffic at the last second. The oncoming traffic had to brake and honked. After reading online, this is a common issue with the 6l80 transmission torque converters being a failure point and the fluid temperature being too high. Gm has a service bulletin for a lower temp bypass valve but there is no recall and these units are failing by the tens of thousands.

Just purchased this vehicle used from a business in Moyock, NC. The mileage at purchase was 92,860. We checked Carfax and it showed two previous owners and had a steady maintenance history. On the way home (2 hour drive) and after the vehicle had warmed up it started showing signs of transmission problems. This was not noticeable on the test drive. The RPMs skyrocketed, the car went into neutral, once we got it back into gear it would hardly accelerate. It was a long long drive home! We took it to our local mechanic and must replace the transmission at a cost of $7,000. We will not use the manufacturer's transmission product as a replacement after reading all the complaints that are so similar to ours. Definitely not what we were expecting to have to do within a week of the purchase. There could have been injuries if my wife had not been following me and knew something was wrong when the vehicle slowed down significantly. No one was injured, except for our pride and wallet.

I had just slowed down to pull into work, stepped on the gas and the suburban started chugging. After pulling into a parking space I could no longer more forward in Drive. After shifting through all the gears, I no longer had reverse, and to move my vehicle off to the side for the tow company, I had to put it in Nuetral to go forward. I had no warning lights on the dash, no errors when a mechanic scanned it. It obviously needs a new 6L80 transmission, which I see a similar class action suit for. The only blessing is that, by chance, my kids were not in our family vehicle when the tranmission broke. I had driven them to and from school just hours earlier. And that I made it safely to work, not broken down on the side of any busy roads.

We purchased this vehicle from a local dealership (2/5/2024) and 25 days after purchasing it (3/1/2024) we had to have it towed as the torque converter and transmission went out and we could no longer drive it. This was quite costly at $6600.00.
