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.
