Installation Procedure

    Notice: Automatic transmission oil cooler flushing must be performed when an automatic transmission is removed for service. The flushing procedure should be performed after the installation of the overhauled or replacement transmission. Failure to flush the system may cause damage to the system and its components.

  1. Flush the transmission oil cooler. Refer to Transmission Fluid Cooler Flushing and Flow Test .
  2. Install the transmission.
  3. Apply thread locking compound to the transmission housing to engine bolt threads.

    4. Notice: Refer to Fastener Notice in the Preface section.

  4. Install the transmission housing to engine bolts.

    5. Tighten
    Tighten the transmission housing to engine block bolts to 60 N·m (44 lb ft).

  5. Test the torque converter for freedom of rotation.
    6. • The torque converter must rotate freely.
    • If not, the torque converter is not fully seated in the pump drive gear. Perform the following:
         1. Remove the transmission.
         2. Inspect the transmission pump gears for damage, repair as needed.
         3. Install the torque converter. The torque converter must be fully seated.
         4. Install the transmission.
  6. Remove the support from the front of the engine.
  7. Connect the electrical connectors at the following locations:
    8. • The transmission control selector switch
    • The transmission adapter case
    • The transmission main case
    • The transmission speed sensor
    • Attach the harness clip to the housing
  8. Install the transmission vent hose.
  9. Raise the transmission into position.

    10. Object Number: 159592 Size: SH
  10. Install the crossmember.
  11. Install the crossmember to body bolts (2).

    12. Tighten
    Tighten the crossmember to body bolts to 45 N·m (33 lb ft).

  12. Install the crossmember to transmission mount nuts (1).

    13. Tighten
    Tighten the transmission mount nuts to 20 N·m (15 lb ft).

  13. Remove the transmission support.

    14. Object Number: 159713 Size: SH
  14. Install the transmission housing to engine oil pan bolts (1).

    15. Tighten
    Tighten the transmission housing to engine oil pan bolts to 20 N·m (15 lb ft).

  15. Install the exhaust catalytic converters. Refer to Exhaust System Replacement .

    16. Object Number: 159627 Size: SH
  16. Connect the oxygen sensor connectors (1).

    17. Object Number: 159415 Size: MH
  17. Install the transmission oil cooler inlet (1) and outlet (2) pipes.
    18. • Connect the hoses on the pipes.
    • Squeeze the clamps.
    • Slide the clamps toward the hose connection.

    Important: Install and only finger tighten all six flywheel to torque converter bolts.


    Object Number: 158346 Size: SH
  18. Install the new flywheel to torque converter bolts:
    19. • Remove the retaining compound from the first three threads of the new flywheel to torque converter bolts.
    • Observe the marks made during disassembly and align in original position.
    • Ensure weld nuts on torque converter are flush with flywheel.
    • Tighten the torque converter bolts.

    Tighten
    Tighten the flywheel to torque converter bolts to 30 N·m (22 lb ft).


    Object Number: 159703 Size: SH
  19. Install the access hole plugs on the following components:
    20. • The transmission oil pan (1)
    • The bell housing (2)
  20. Install the propeller shaft coupling to the drive flange.

  22. Install the shift linkage. Refer to Shift Control Linkage Replacement .
  23. Adjust the shift linkage. Refer to Shift Control Linkage Adjustment .
  24. Fill the transmission with DEXRON® VI. Refer to Transmission Fluid Check .
  25. Lower the vehicle.

    26. 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.

  26. Reset the TAP values. Refer to Transmission General Description .
