2. Remove the old transmission filter and replace it with a new one.
3. Clean the pan and apply a new gasket if necessary.
4. Reinstall the transmission pan and torque the bolts to the manufacturer’s specifications.
Tools Required: Torque wrench, gasket scraper.
Safety Warnings: Use gloves when handling transmission fluid to avoid skin irritation.

4. Repair or Replace Transmission Control Module (if needed)

Sub-steps:
1. Disconnect the electrical connectors from the TCM.
2. Remove the TCM from its mounting location.
3. Install the new TCM (if replacement is needed) and reconnect the wiring.
