Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and the engine is off.

Lift the vehicle using a jack and secure with jack stands.
Check for any visible leaks around the transmission pan and seals.
If leaks are found, tighten bolts or replace gaskets as necessary.

5. Check Reverse Light Switch

Locate the reverse light switch on the transmission.
Disconnect the wiring harness and test the switch using a multimeter.
