2017 Chevrolet Tahoe: shudder or vibration when accelerating

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.

Just over 115,xxx miles and the transmission is shuddering, difficulty with taking off, RPMs are not steady, delayed acceleration due to sputtering. When at signal light it acts as if it is not going to take off, which could cause other vehicles to rear end my vehicle.

About 3 weeks ago my vehicle began shuddering during acceleration only at low speeds, and I had an appointment to regularly scheduled maintenance next week and planned to have the dealer look at it during that appointment. However, 3 days ago, at about 84,479 miles I was merging on to the highway and when I attempted to accelerate to highway speeds the tachometer jumped to 6000 rpm’s and became very sluggish when accelerating. It calmed down, but shortly after calming down, the tachometer spiked again to around 4500 rpm’s at 70mph, the check engine light came on and the vehicle temporarily stopped responding to any input except to raise the tachometer reading. After shifting into manual and back into automatic the transmission reengaged but would not allow for normal acceleration. The vehicle was able to be driven at approximately 30-35mph while the tachometer stayed consistently at around 3500-4000 rpm’s. The trouble codes given were P0700 and P0796, both relating to transmission indicating a problem with it.

Shake/shudder while driving straight on highway at 72 MPH up to at least 90 MPH. Steering wheel, center counsle, and seats shake. Goes away when not accelerating. Balanced tires and did not fix. Dealer then balanced tires and alignment was completed. This also did not fix. Dealer kept my car for almost 2 weeks and replaced torque converter. This still did not fix it. Have to take it in for a 3rd time. Make me feel dizzy and nauseous.
