22. Lower the vehicle.
23. Fill the transmission to the proper level with DEXRON® VI transmission fluid. Refer to Transmission Fluid Check .

Important: It is recommended that transmission adaptive pressure (TAP) information be reset.

Resetting the TAP values using a scan tool will erase all learned values in all cells. As a result, The ECM, PCM or TCM will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned.
24. Reset the TAP values. Refer to Adapt Function .
