Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, 10mm socket wrench.
Remove the transmission fluid dipstick and check the fluid level.
If fluid is low, add the recommended type of transmission fluid (consult owner's manual).
If the fluid is dirty or burnt, drain the old fluid using a pump and replace it with new fluid.
Reconnect the dipstick and secure it properly.

3. Inspect and Adjust Gear Linkage

Tools Required: Socket set, pliers, and a screwdriver.
Locate the gear linkage under the vehicle; ensure it is properly connected to the transmission.
Adjust the linkage if it is misaligned or replace any damaged components.

4. Replace Brake Switch (if faulty)

Tools Required: Socket set, wire connectors, and electrical tape.
Locate the brake switch, usually found near the brake pedal assembly.
Disconnect the wiring harness and remove the switch.
Install the new brake switch and reconnect the wiring harness.

5. Reconnect Battery

Once all repairs are completed, reconnect the negative battery terminal.
Ensure all connections are tight and secure.
