2017 Chevrolet Tahoe: complete transmission failure

Filed Jun 13, 2026 · Transmission · SC

My 2017 Chevrolet Tahoe equipped with a 6L80 transmission began experiencing transmission-related drivability issues at approximately 130,000 miles. The vehicle jerked on takeoff, had delayed/slow shifting, produced a whining noise, and later had intermittent shuddering/surging while driving. During service, metallic debris/shavings were found in the transmission fluid. The transmission ultimately required replacement at my expense. I am aware of GM Technical Service Bulletin 20-NA-142, “Shudder/Surging While Driving,” which includes 2015–2022 Chevrolet Tahoe models equipped with MYC/MYD transmissions and discusses conditions that may be identified as torque converter shudder. My vehicle’s 6L80 transmission corresponds with GM RPO MYC, and the symptoms/repair findings appeared consistent with the bulletin. I am filing this complaint to document the transmission failure and related safety concern, as the jerking, delayed shifting, and shuddering affected normal vehicle operation.

The transmission dropped 2 thousand miles over my warranty at 102k miles. I was taking my son to see his surgeon and the car started jerking and making noises in the middle of a busy intersection. We almost got hit several times trying to get it to the side of the road for safety. I had to pay almost $1800 to get it towed home (we were in Peoria about 150 miles from home to see his doctor). There were no indications the transmission was going out and never should have at that mileage. I always do regular maintenance and keep all my receipts. I then paid 6k out of pocket to have it replaced with a better transmission since I learned GM put a bad transmission in the Tahoe I have (I was told I missed the time limit to have it fixed on their dime). Then 6 weeks later a fuel injector and the lifters failed due to the active fuel management. No one was hurt thankfully because I was just leaving home to go to work when I noticed the tapping sound and had my mechanic come look at it. Him and 2 other mechanics confirmed it was the lifters. I had already borrowed money to replace the transmission and can’t afford the $12k quote to fix it. Now it has been sitting in my driveway for almost a year unable to be driven. It is however causing me severe depression. I’m borrowing my son’s car while paying almost $700 monthly on a Tahoe I can’t even drive. I was even more sad when I found out there’s thousands of people with the same issue. GM should be ashamed of themselves!

I purchased this Tahoe in 2021I believe. I have replaced the transmission in 2024 for this Z71 Tahoe and now the lifters are gone as well. In the process of going in the shop. I’m very upset. Tahoe’s cost too much for transmission, lifters to be going out and needing a new one installed. This is a major problem with Tahoe’s and I need some answers as to what can be done to help with this major issue. Who do I need to call or speak with to get this issue resolved. It’s a problem and no one wants to be accountable for making trash and selling it at high price for the consumer to pay for Chevrolet mistakes. Something must be done!!!

My transmission is slipping and causing safety concerns while driving on the highway. It’s a 2017 Chevy Tahoe that has less than 100,000 miles and we have been reading on the internet about many others having the same problem. We just took it to a shop and they informed us that it’s a common issue with this model chevy and it will cost $5,000 to replace the transmission.

In 2022, I had to have cylinders 1-7 replaced. At the time, these vehicles were known to have transmission problems. My vehicle was 3,000 over warranty and Chevy denied any fault and only reimbursed me half of the $1500 to get replaced. Today, my complete transmission failed. Two years later. Chevy denied any fault regardless of lawsuits filed. Is going to cost $6300 for total replacement. I have NEVER in my life had transmission issues on a vehicle--especially so early in the life of the vehicle. The car almost left me stranded on the side of the interstate. Chevy knows about this problem and will not make good on a vehicle I paid over $60000 for.

The transmissions stopped working while my wife was driving. The car stopped in the intersection. She was able to shut it off and it restarted so that she could pull into a parking lot. Car was towed to the dealer. The car has 74,000 miles on it and we were told it needs a new transmission and that it would cost $6900 to repair. I called GM and filed a claim with them in hopes they would offer some assistance. I was told nothing could be done. I have since spoke to several repair shops and checked the internet and have found out that it seems GM is having this problem often, for the years 2015-2017 for the Tahoe, Yukon, and Silverado.
