NOTE: 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 or TCM will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned.

Reset the TAP values. Refer to Transmission Adaptive Functions .
