I have a 2019 Equinox Premier AWD with the 2.0L Engine and 9 speed transmission. At around 67,000 miles, the transmission started shuddering as it was shifting through 3-5th gears. Took it to the dealership where vehicle was purchased, and they diagnosed a bad transmission. Paid a lot of money to have it replaced. Picked up vehicle and within 100 miles, this transmission is doing the same thing. There are no engine codes showing and the text stated there were no codes showing for tranny either. At normal speeds, everything is smooth. What are some other possibilities? I am very frustrated at this time. Also, all services are up to date including new spark plugs to rule that out.

Was the shudder happening under hard acceleration or normal driving? Mine will shudder slightly under hard acceleration around 4th gear. I think it is so close to third that when it shifts it almost feels like it slows down before hitting 5th. Just a quirk, there is nothing mechanically wrong with my 'nox. If i am accelerating normally it doesn't do it.

I wonder if this is nothing more than the driveline wobble or vibration many of us have experienced with our 2018+ due to CV shaft "runout". Search TSB #20-NA-227. My 2021 got "fixed" for free for this concern in 2024 with ~35K miles on it. It didn't entirely fix it, but it's much better. Currently have 47K miles on it.

It is not in my case, but good thought. Have you ever noticed how it will stay in a gear to help decelerate when going down a hill. That's how mine feels, like the momentum is pushing the gearing faster than the motor is spinning for a brief second. It doesn't really concern me that much. It could even be that the throttle body needs cleaned.
