Tools Required

1. Remove the control valve body. Refer to Valve Body .



2. Remove the accumulator cover bolts.
3. Remove the 1-2 accumulator cover and pin, piston, and springs.



4. Remove the 1-2 accumulator piston spring.
5. Remove the 1-2 accumulator piston, and the oil seal ring.



6. Remove the oil pass cover bolt.
7. Remove the oil pass cover.



8. Remove the spacer plate.
9. Remove the spacer plate gaskets.



10. Remove the 3-4 accumulator spring.
11. Remove the piston oil seal ring.
12. Remove the 3-4 accumulator piston, and the pin.
13. Inspect the accumulator assembly.

1. Install the 3-4 accumulator pin into the transmission case.
2. Install the 3-4 accumulator piston onto the pin. The piston legs must face the valve body.
3. Install the 3-4 accumulator piston oil seal ring.
4. Install the 3-4 accumulator piston spring.
5. Install the J 25025-B to the transmission case.



6. Install the case gasket and the valve body gasket to the spacer plate. The case gasket is identified by a C. The valve body gasket is identified by a V.
7. Use the J 36850 in order to retain the gaskets to the spacer plate.



8. Install the spacer plate and the gaskets to the transmission case.

Notice: Refer to Fastener Notice in the Preface section.




9. Install the oil pass cover and the oil pass cover bolts.

Tighten
Tighten the bolts to 11 N·m (97 lb in).




10. Install the 1-2 accumulator piston with the piston legs facing toward the case.
11. Install the oil seal ring to the accumulator cover.
12. Install the 1-2 accumulator spring onto the piston.



13. Install the 1-2 accumulator cover and the cover bolts.

Tighten
Tighten the bolts to 11 N·m (97 lb in).

14. Remove the J 25025-B from the transmission case.
15. Install the control valve body. Refer to Valve Body .

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,
16. Reset the TAP values. Refer to Adapt Function .
