Solution

1. Preparation

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

2. Check and Top Off Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe it clean, reinsert, and remove it again to check the fluid level.
If low, add the appropriate transmission fluid (refer to the owner's manual for specifications).

3. Inspect and Adjust Transmission Linkage

Locate the transmission linkage connected to the gear shifter.
Check for loose, broken, or misaligned components.
If misaligned, adjust the linkage according to the manufacturer’s specifications, ensuring proper connection.

4. Replace or Repair the Brake Switch

Locate the brake switch, typically found near the brake pedal.
If faulty, disconnect the electrical connector and remove the switch.
Install a new brake switch and reconnect the electrical connector.

5. Inspect Transmission for Internal Issues

If the previous steps do not resolve the issue, drain the transmission fluid and remove the transmission pan.
Inspect for metal shavings or debris, indicating internal wear.
If damage is found, consider rebuilding or replacing the transmission.
