- Install the pressure regulator valve (1).
- Install the pressure regulator isolator spring (3) and the pressure regulator valve spring (2).
- Install the reverse boost valve (4) in the reverse boost valve sleeve (5).
- Install the reverse boost valve (4) and sleeve (5) in the oil pump cover.
- Compress the reverse boost valve sleeve into the bore of the oil pump to expose the retaining ring slot.
- Install the reverse boost valve retaining ring, then slowly release tension on the reverse boost valve sleeve.
- Install the transmission filter. Refer to Automatic Transmission Fluid and Filter Replacement .
- Reset the TAP values. Refer to Transmission Adaptive Functions (TCM) .
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.
