Ensure the vehicle is on a level surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick (if equipped) or access the fill plug.
2. Remove the dipstick or fill plug and check the fluid level; add fluid if low.
3. Inspect the fluid's condition; if it’s dark or smells burnt, a fluid change is needed.
Safety Warnings: Allow engine to cool before working on the transmission.

3. Inspect Linkage

Sub-steps:
1. Visually inspect the transmission linkage for damage or disconnection.
2. Adjust or replace any misaligned or broken linkage components as necessary.
Tools Required: Socket set, pliers.

4. Test Brake Switch

Sub-steps:
1. Locate the brake switch near the brake pedal.
2. Test the switch for continuity using a multimeter; replace if faulty.
Tools Required: Multimeter.

5. Fluid Change (If Necessary)

Sub-steps:
