  7. Install the transmission wiring harness on the valve body.
    8. CAUTION: Refer to Fastener Caution .
  8. Install the TCC solenoid valve and bolts (68).

    Tighten the bolts to 814 N.m (610 lb ft).

    9. Fig 6: Identifying Bolt Locations

    CAUTION: Do not over-tighten the bolts. Over-tightening the bolts will distort the valve bores. Begin tightening from the center of the valve body tighten the bolts in a outward direction.
  9. Inspect the ensure all of the valve body bolts are in the correct location. Each bolt number refers to a specific size, as indicated in the following list:
    • 59 M6 x 1.0 x 35.0 (Qty: 2)
    • 62 M6 x 1.0 x 47.5 (Qty: 12)
    • 120 M6 x 1.0 x 54.4 (Qty: 3)
  10. Tighten the bolts from the center of the valve body working your way out in a spiral pattern to the outside edge.

    Tighten the bolts to 814 N.m (610 lb ft).

    11. Fig 7: View Of TCC/PWM Solenoid & Clip

  11. Install the TCC PWM solenoid valve (396) and the solenoid retainer (395).
    12. Fig 8: Electrical Connectors

  12. Snap the wiring harness in place on the valve body bolts. Ensure the harness loom tab is located under the transmission fluid pressure (TFP) switch.
  13. Install the wiring connectors to the electrical components (1-6) as indicated in the following list:
    1. The manual shift detent lever with shaft position switch assembly
    2. The 1-2 shift solenoid
    3. The 2-3 shift solenoid
    4. The pressure control solenoid (PCS)
    5. The TCC PWM solenoid
    6. The input speed sensor (ISS)
  14. Install the transmission oil pan and filter. Refer to Automatic Transmission Fluid and Filter Replacement .
  15. Lower the vehicle.
  16. Fill the transmission to the proper level with DEXRON® VI transmission fluid. Refer to Transmission Fluid Check .
    17. NOTE: 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.
  17. Reset the TAP values. Refer to Transmission Adaptive Functions .
