- Inspect the 4th apply piston, 2-4 servo converter, 2nd apply piston, and the servo piston inner housing for the following defects.
- Disassemble the 2-4 servo if necessary. Refer to
2-4 Band Servo 2nd Apply Piston Disassemble
.
- Clean and inspect the 2-4 servo. Refer to
2-4 Band Servo Piston Pin Length Check
.

.
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
.
