• Clean any corroded connectors with a wire brush and apply dielectric grease before reassembling.

4. Replace Transmission Control Module (if necessary)

• Tools Required: Socket set, torque wrench
• Locate the TCM, typically found in the engine compartment or under the dashboard.
• Disconnect the wiring harness from the TCM.
• Remove the TCM by unscrewing the mounting bolts (refer to the service manual for torque specifications).
• Install the new TCM, ensuring proper alignment and secure mounting.
• Reconnect the wiring harness.

5. Reset the Check Engine Light
