1. Remove the transmission fluid pan by unscrewing the bolts using a socket set.
2. Drain the old transmission fluid into a suitable container.
3. Clean the transmission pan thoroughly and replace the filter if applicable.
4. Reinstall the pan and torque bolts to manufacturer specifications (typically around 10-12 Nm).
5. Refill the transmission with the recommended fluid type (consult owner’s manual for specifications).

3. Inspect and Repair Wiring

Sub-steps:
1. Locate the TCM and inspect the wiring harness for any damage or corrosion.
2. Clean any corroded connectors and ensure all connections are secure.
3. If any wires are damaged, repair or replace them with appropriate gauge wire.

4. Software Update (if required)

Sub-steps:
