I have a 2017 ltz which I’ve had issues with the transmission ever since I got it. I’ve had the fluid flush 3 times new torque converter. Harness replaced. The Fast learn twice. Now the valve body sounds like they’re going to replace it if the dealership lifetime powertrain warranty will kick in and cover it. Otherwise it’s going down the road. I’m done with it.
