      Be sure to place the case gasket on the transmission case side of the spacer plate.

    • The valve body gasket is identified by a V.

      Be sure to place the valve body gasket on the valve body side of the spacer plate.

  6. Ensure that the solenoid screens (1, 2) are in place on the spacer plate.
  7. Place the checkball (3) on the spacer plate in the location shown.
  8. Place the 3-4 accumulator spring (4) on the spacer plate.
  9. Install the spacer plate and related components to the transmission.

    IMPORTANT: RPO M33 transmissions do not use a 1-2 accumulator spring inner (104).
  13. Assemble the 1-2 accumulator assembly (54, 56, 57, 104). Ensure that the piston legs face the accumulator cover.
  14. Install the 1-2 accumulator cover (57) and pin.
    15. Fig 10: View Of 1-2 Accumulator Cover & Bolts

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

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

  16. Remove the J 25025-B  from the transmission case. See Special Tools .
  17. Install the valve body. Refer to Valve Body and Pressure Switch Replacement .
  18. Install the transmission filter. Refer to Automatic Transmission Fluid and Filter Replacement .
    19. 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 engine control module (ECM), powertrain control module (PCM) or transmission control module (TCM) will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned.
  19. Reset the TAP values. Refer to Transmission Adaptive Functions (TCM) .
