Removal Procedure
- Remove the air cleaner intake duct. Refer to Air Cleaner Inlet Duct Replacement in Engine Controls - 3.1L or Air Cleaner Inlet Duct Replacement in Engine Controls - 3.8L.
- Depress the reverse servo cover (40).
- Remove the snap ring (39).
- Pull the O-ring seal (41) out through the slot in the case.
- Use side cutting pliers in order to cut the servo cover O-ring seal (41).

- Reset the TAP values. Refer to Transmission Adaptive Functions .
Important: Follow this procedure exactly or the transaxle will have no reverse gear due to the servo pin missing the band.
Important: It is recommended that the 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 the TAP values. Transmission performance may be affected as new TAP values are learned.
