I first noticed mine around 400 miles, and now I notice it daily as I’m aware of the issue. I called the dealer today and talked to a service representative and he told me the transmission is “Learning” and to wait after a 1000 miles to bring it in if its still occurring. I’m almost 100% sure the issue is the torque convertor after doing some research on the issue. GM released a service announcement of some sort on the issue. Search “#PIP5337C: Shake or Shudder Between 30 and 65mph” for 2015-2016 models, there is hardly anything on 2017 models but after I read this document my truck has all these symptoms. I’m going to wait until the 1000 mile mark before I call the dealership and take it in.
