Removal Procedure
1. Remove the transmission filter. Refer to Automatic Transmission Fluid and Filter
Replacement.
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 TCM will
need to relearn TAP values. Transmission performance may
be affected as new TAP values are learned.
