What owners report
The 6-speed automatic transmission (6L80) developed a severe shudder during normal driving. A service center diagnosed the problem as torque converter clutch failure; the torque converter sheds metal debris through the transmission, so the transmission now requires a full rebuild quoted at approximately $6,000. The failure occurred at approximately 92,000 miles in October 2026 (incident date is approximate). This is a widely documented failure pattern on GM 6L80 transmissions. Loss of reliable power delivery from the transmission is a safety concern. No crash, no injuries, and no fire occurred. The vehicle is available for inspection upon request.
In August, 2019, at 93,672 miles, GM covered a lifter failure on our 2015 GMC Sierra, V8 AFM engine. Only the left side was repaired. Now, in 2026 at 130,000, the right side has the same issue and needs repair. The estimate to repair is $16,697. This is a known issue and a safety concern.
The transmission Started Shuddering, it would slip occasionally and slipped badly when i was driving in rush hour traffic in the middle of a left turn. had no power for several seconds then it finally reengaged. The shuddering got worse and worse to the point i took it to a transmission shop to look at it and they said i needed a replacement transmission unit. I did get a replacement unit, the whole process was extremely unpleasant. The previous unit was sent as a core to be remanufactured. The company that i used to get a remanufactured unit is Fraser Transmissions. No warning lamps appeared prior to the transmission acting up.
Power steering seems to be lost for a second or two at low speeds turning. Happens multiple times a day.
My 2015 GMC Sierra 1500 recently started having all the symptoms under GM internal recall number 18289. I lose my power steering briefly and the electronics turn off momentarily. I lose dash, AC, radio and GPS. It comes back on within a second or two and only does this during low speed turning. I ran my VIN but it does not show under this recall despite having the correct Make/Model/Year. It is currently at the shop because it isn't safe to drive and I was hoping I could get a reimbursement for the repairs. NHTSA Campaign Number: 18V586000 (GM's Internal Number: 18289)
