Removal Procedure
- Remove the transmission filter. Refer to
Automatic Transmission Fluid and Filter Replacement
.
- Compress the reverse boost valve sleeve into the bore of the oil pump to release tension on the reverse boost valve retaining ring.
- Remove the reverse boost valve retaining ring, then slowly release tension on the reverse boost valve sleeve.
- Remove the reverse boost valve sleeve (5) and the reverse boost valve (4).
- Remove the pressure regulator isolator spring (3) and the pressure regulator valve spring (2).
- Remove the pressure regulator valve (1).
Installation Procedure
- 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

.
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.
- Reset the TAP values. Refer to
Transmission Adaptive Functions
