Tools Required: Transmission jack, drain pan, socket set, funnel, new transmission fluid, new filter (if applicable).
Use the drain pan to catch old fluid once the transmission pan is removed.
Remove the transmission pan bolts using the socket set, then carefully lower the pan.
Replace the old filter with a new one if applicable.
Clean the transmission pan and install a new gasket.
Refill the transmission with the correct type and quantity of fluid using the funnel.

3. Inspect and Repair Wiring

Tools Required: Multimeter, electrical connectors.
Check the wiring harness for continuity and shorts using the multimeter.
Repair or replace any damaged wires or connections.

4. Reprogram Transmission Control Module (if necessary)

Tools Required: OBD-II scanner capable of reprogramming.
Connect the OBD-II scanner and follow the manufacturer’s instructions to reprogram the transmission control module.
