    IMPORTANT: When installing bolts throughout this procedure, be sure to use the correct bolt size and length in the correct location as specified.
  5. Do not install the transmission fluid indicator stop bracket and bolt at this time.

    Install but do not tighten the control valve body bolts which retain only the valve body directly.

    Each numbered bolt location corresponds to a specific bolt size and length, as indicated by the following:

    • M6 X 1.0 X 65.0 (1)
    • M6 X 1.0 X 54.4 (2)
    • M6 X 1.0 X 47.5 (3)
    • M6 X 1.0 X 35.0 (4)
    • M8 X 1.0 X 20.0 (5)
    • M6 X 1.0 X 12.0 (6)
    • M6 X 1.0 X 18.0 (7)

  8. Install the transmission fluid pressure switch.
  9. Install but do not tighten the control valve body bolts which retain the transmission fluid pressure switch to the control valve body.
    10. NOTE: Refer to Fastener Notice in Cautions and Notices.
    NOTE: Torque valve body bolts in a spiral pattern starting from the center. If the bolts are torqued at random, valve bores may be distorted and inhibit valve operation.

  19. Connect the internal wiring harness electrical connectors to the following components:
    • The transmission fluid pressure manual valve position switch (1)
    • The 1-2 shift solenoid (2)
    • The 2-3 shift solenoid (3)
    • The pressure control solenoid (4)
    • The TCC PWM solenoid (5)
    • The 3-2 shift solenoid (6)
  20. Install the transmission oil pan and filter. Refer to Automatic Transmission Fluid/Filter Replacement .
  21. Lower the vehicle.
  22. Fill the transmission to the proper level with DEXRON® VI transmission fluid. Refer to Transmission Fluid Checking Procedure .
    23. 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.
  23. Reset the TAP values. Refer to Transmission Adaptive Functions (TCM) .
