Aug 29, 2025Transmission & drivetrain

6L80 transmission has failed @ 109,000 miles. At a stop light, in drive, vehicle would not move in drive or reverse. After switching back and forth transmission finally started to work and was able to limp to a dealership. Did not realize how big this issue is with this transmission until mine failed prematurely. I thank God that mine happened at a stop light and not when trying to accelerate at a say a stop sign where I need to cross multiple lanes of traffic. I would have been a sitting duck in the middle of oncoming traffic.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2016 GMC Savana Cargo G33405 verdict →
