I own a 2020 Chevy Traverse with currently 16,000 miles. I am currently dealing with a know shudder issue that has returned. I have already taken the vehicle under warranty to the dealership where the transmission was replaced on 6/29/2022 at 4919 miles for “catastrophic failure” where the fluids were dark, burnt, and several burnt up clutches. Then the torque converter was replaced separately on 9/20/2022 at 8106 miles for engine shudder. Took the vehicle again in on 7/21/26 for shudder returning at 16,450k miles where diagnostic shows dark, burnt fluid, with metal debri. Repair recommendations are to flush again and if not fixed to again replace the torque converter. There are no open recalls on my vehicle when there should. There is the most recent bulletin, Bulletin No.: 23-NA-072 dated May 2023 that covers the 2020 Chevy Traverse for TCC Shudder: (Typically seen on 4th-5th Upshift as ISS Oscillation) which is referenced on my last car diagnostic report. This car is basically brand new and should never have needed a brand new transmission, torque converter replacement and still having shudder problems. These vehicles need to be recalled for their power train.

I have 37,000 miles and have taken it to a Chevrolet dealer for all suggested routine maintenance. It started shuddering so I took in to dealer. They said known issue and may need a new torque converter which would cost approximately $8500. They suggested I try changing the transmission fluid even though suggested at 45,000 miles. They said to drive 200 miles and see if it goes away. I haven't yet put 200 miles but am very concerned there is a bigger issue with the Traverses out there and afraid this is a band-aid and feel a recall may be inevitable. Just wanted to share with you.

2020 Chevrolet Traverse started to shudder and hard shift between 25 to 30 miles per hour. Vehicle only has 64,925 miles on it (4,925 miles above warranty). Vehicle was taken to garage and told the torque converter along with valve body was needed to be replaced. The torque converter malfunctioned right after warranty expired due to mileage and could have left my family stranded on the side of the road. The components have been inspected by Chevrolet manufacturer and they deemed they needed to be replaced and replaced them. No lights or anything came on the only sign was the shudder and hard shift which if not taken in immediately could put the owner past the warranty mileage. Vehicle was purchased brand new and routine maintenance conducted.

Receiving a persistent “Shift to Park” message, after the car has been placed in Park. This causes an inability to turn off my engine completely and is draining my battery. As a temp fix, I've had to wiggle the shifter many times, turn the car on and off, place the car from park into drive many times to get the car to realize it's in Park. Scheduled with the dealership and referenced the TSB that was issued for this specific safety issue (in writing). Brought the car in for the repair and the technician and intake person were both aware of this major problem and have seen other Chevy's with the same issue. Repair is $809.00 for a shifter assembly.
