Disconnect the negative battery terminal to ensure safety.

2. Check and Top Off Transmission Fluid

Tools Required: Transmission funnel, clean rag
Steps:
1. Locate the transmission dipstick or fill port.
2. Remove the dipstick, wipe it clean, and reinsert it to check the fluid level.
3. If low, add the recommended transmission fluid (consult the owner's manual for specifications).
4. Check for any signs of fluid contamination.

3. Inspect Transmission Linkage

Tools Required: Socket set, screwdriver
Steps:
1. Remove any covers obstructing access to the transmission linkage.
2. Visually inspect the linkage for any signs of damage or wear.
3. Ensure the linkage is properly connected and adjust if necessary.

4. Brake Switch Inspection

Tools Required: Multimeter
Steps:
1. Locate the brake light switch, usually mounted above the brake pedal.
2. Use a multimeter to check for continuity when the brake pedal is pressed.
3. If the switch is faulty, replace it with a new one.

5. Electrical System Check

Tools Required: Multimeter
Steps:
1. Check the battery voltage; it should be between 12.4V and 12.7V with the engine off.
2. If voltage is low, recharge or replace the battery.
