Note: The Transmission Adaptive Values Learn procedure must be performed when one of the following repairs have been made to the vehicle. Failure to perform the procedure after one of the following repairs may result in poor transmission performance, as well as transmission DTCs being set:
* Transmission internal service/overhaul
* Valve body repair or replacement
* Control solenoid valve assembly replacement
* TCM software/calibration update
* Any service in response to a shift quality concern
