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 in Engine Electrical.
- 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 in Engine Electrical.
- Reprogram the TCM. Refer to Transmission Control Module Reprogramming .
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Tighten
Tighten the bolts to 9 N·m (80 lb in).
