Installation Procedure





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 (Control Valve Body Replacement) .
* Install the transmission side cover. Refer to Control Valve Body Cover Replacement (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 (Transmission Adaptive Functions) .
