Installation
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 engine control
module (ECM), powertrain control module (PCM), or
transmission control module (TCM) will need to relearn TAP
values. Transmission performance may be affected as new
TAP values are learned.
NOTE:
For ON-VEHICLE repair information, see ON-VEHICLE REPAIR
INSTRUCTIONS. OFF-VEHICLE repair information is covered below.
