2023 Chevrolet Traverse power train problems

“-The Torque Converter Clutch (TCC) inside the automatic transmission is malfunctioning. It is experiencing a known defect outlined in GM Service Bulletin 23-NA-072. The vehicle is still being driven and is available for inspection upon request. -The transmission violently shudders and vibrates under light acceleration at low speeds (such as pulling out into traffic, merging, or navigating intersections). This violent, unexpected shaking creates a distraction, mimics the feeling of a blown tire or driving over a rumble strip, and causes hesitation in acceleration, which creates a safety hazard when merging with oncoming traffic. -The problem has been consistently reproduced by the owner. It matches the exact diagnostic criteria of GM’s active Technical Service Bulletin for TCC shudder. -No, it has not been inspected. - No check engine lights, warning lamps, or dashboard messages have appeared. The physical symptom is a severe mechanical shudder/vibration at low acceleration speeds, which first began appearing at approximately 75,000-80,000 -”

“My 2023 traverse rs experienced a loud grinding noise and sudden loss of power, almost like i slammed the brakes on while moving. I was in the middle of the road and i could have been rear ended. 10/12/26. This matches the GM recall N222389310 exactly but my vin is currently excluded. I am also experiencing a heavy vibration since 9/13/2026 similar to diving over rumble strips, it is intermittent and will not throw a code, its been to the GM dealership where new transmission fluid was put in, however started again, that did not solve the problem . GM does not have a recall for torque converter clutch they are aware and had put out a technical service bulletin TSB-23-NA-072.”

“I own a 2023 Chevrolet Traverse. While driving, the vehicle suddenly began jerking very hard during acceleration and shifting. The Check Engine Light illuminated, and the vehicle became unsafe to drive because the transmission was not operating normally. I was concerned that the vehicle could suddenly lose power or fail while driving in traffic, increasing the risk of a crash. I took the vehicle to a Chevrolet dealership for diagnosis. The dealer found the transmission fluid was burned and diagnosed transmission trouble codes P0797 and P0700, indicating an internal transmission problem.
