Object Number: 768690  Size: SH

Connect the wiring harness assembly to the following components:

    • The TFP switch assembly (13)
    • The pressure control solenoid (312) (red connector)

       Important: The 1-2 shift solenoids wires are red and light green. The 2-3 shift solenoid wires are red and yellow.

    • The 1-2 shift solenoid (305) (white connector)
    • The 2-3 shift solenoids (305) (white connectors)
    • The TCC solenoid (335)
    • Install the control valve body. Refer to Control Valve Body Replacement .
    • Install the transmission side cover. Refer to Control Valve Body Cover Replacement .

       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.

    • Reset the TAP values. Refer to Transmission Adaptive Functions .
