Control Module: Service and Repair

Transmission Control Module Replacement

Removal Procedure

1. Turn the ignition OFF.




2. Remove the air cleaner upper cover.




3. Remove the transmission control module (TCM) from the air cleaner.
4. Disconnect the TCM electrical connectors from the TCM.

Installation Procedure




1. Connect the TCM electrical connectors to the TCM.
2. Install the TCM to the air cleaner.




3. Install the air cleaner upper cover.
4. Program the TCM.

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 TCM will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned.

5. Reset the TAP values.
