Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid pump, transmission fluid, cleaning cloths.
Ensure the vehicle is on a level surface and securely parked with the parking brake engaged.
Disconnect the battery before working on electrical systems.

2. Check Transmission Fluid

Locate the transmission dipstick or fill port.
Remove the dipstick or fill plug and clean it with a cloth.
Insert it back and remove to check the fluid level.
If low, add the appropriate transmission fluid (check manufacturer specifications).

3. Inspect Gear Selector Linkage

Remove any covers or panels obstructing access to the gear linkage.
Visually inspect the linkage for any signs of wear or misalignment.
Adjust or replace any damaged components according to the manufacturer’s specifications.

4. Test the Brake Light Switch

Locate the brake light switch near the brake pedal.
Use a multimeter to test for continuity when the brake pedal is pressed.
If faulty, replace the brake light switch.

5. Inspect Transmission

Check for any external leaks around the transmission casing and seals.
If leaks are found, replace any damaged seals or gaskets.
If the transmission is internally damaged, consider seeking professional assistance for repair or replacement.
