Removal Procedure

    Object Number: 181573 Size: SH
  1. Remove the transmission oil pan and filter. Refer to Automatic Transmission Fluid and Filter Replacement .

    2. Important: Do not remove the valve body for the following procedures. Removal of the 1-2 accumulator is necessary only if servicing the pressure control solenoid.

  2. Remove the 1-2 accumulator if necessary. Refer to Accumulator Assembly, Spacer Plate, and Gaskets .
  3. Disconnect the internal wiring harness electrical connectors from the following components:
    4. • Transmission fluid pressure switch (1)
    • 1-2 shift control solenoid (2)
    • 2-3 shift control solenoid (3)
    • Pressure control solenoid (4)
    • TCC PWM solenoid (5)
    • 3-2 control solenoid (6)

    Object Number: 298162 Size: SH

    Object Number: 298162 Size: SH
  5. Install the pressure control solenoid.

    6. Ensure that the electrical tabs are facing outboard.

  6. Install the pressure control solenoid retainer and retaining bolt.

    7. Tighten
    Tighten the pressure control solenoid retaining bolt to 11 N·m (97 lb in).


    Object Number: 181573 Size: SH
  7. Connect the internal wiring harness electrical connectors to the following components:
    8. • Transmission fluid pressure switch (1)
    • 1-2 shift control solenoid (2)
    • 2-3 shift control solenoid (3)
    • Pressure control solenoid (4)
    • TCC PWM solenoid (5)
    • 3-2 control solenoid (6)
  8. Install the 1-2 accumulator. Refer to Accumulator Assembly, Spacer Plate, and Gaskets .
  9. Install the transmission oil pan and filter. Refer to Automatic Transmission Fluid and Filter Replacement .
  10. Fill the transmission to the proper level with DEXRON® VI transmission fluid. Refer to Transmission Fluid Check .

    11. 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.

  11. Reset the TAP values. Refer to Adapt Function.
