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

    Install but do not tighten the 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)
    10. Fig 9: Identifying Manual Detent Spring

  22. 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)
  23. Install the transmission filter. Refer to Automatic Transmission Fluid and Filter Replacement .
    24. 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.
  24. Reset the TAP values. Refer to Transmission Adaptive Functions (TCM) .
