I actually had that done to my 2017 and it was much better after the TSB. When I started experience harsh shifts again I thought it was recurring but found it was another issue with O2 sensor causing it. SInce the O2 sensor is fixed, seems to be back to smooth shifting with the TSBWhat is your build date? There was a TSB with a calibration update released for vehicles build on or before August 1st 2017 to resolve harsh and delayed shift concerns.
