Removal Procedure
Important:
• Remove any debris from the transmission control module (TCM) connector surfaces before servicing the TCM. Inspect the TCM module connector gaskets when diagnosing or replacing the TCM. Ensure that the gaskets are installed correctly. The gaskets
prevent contaminant intrusion into the TCM. • The ignition must be OFF when disconnecting or reconnecting power to the TCM.
- Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .
- Remove the TCM cover bolts (1) located on the left side of the radiator shroud.
- Pull the cover and TCM up and away from the radiator shroud.
- Push up on the retainers (1) in order to remove the TCM from the cover.
- Disconnect the TCM electrical connectors (2) and remove the TCM from the vehicle.
Installation Procedure
- Connect the TCM electrical connectors (2) to the TCM.
- Install the TCM to the cover.
- Using the alignment tabs (1), install the cover and module to the radiator shroud.
- Install the TCM cover bolts (1) to the radiator shroud.
- Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .
- Reprogram the TCM. Refer to Control Module References .
- Perform the FastLearn procedure. Refer to FastLearn Procedure .
Notice: Refer to Fastener Notice in the Preface section.
Tighten
Tighten the bolts to 9 N·m (80 lb in).
Important: The FastLearn (adapt) procedure must be performed. This can be done in one step using a scan tool. If this procedure is not done, the TCM adaptive values will be at the settings that it learned for the old components. and will be in slow adaptive mode. Under these conditions, it would take an unacceptably long time for the adaptive values to converge to levels suitable for the new transmission.
