Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and the parking brake engaged.

2. Check Transmission Fluid

Locate the transmission dipstick. Remove it and wipe clean.
Reinsert the dipstick and remove it again to check the fluid level.
If low, add the appropriate type of transmission fluid (consult the owner’s manual for specifications).
If fluid appears dark or has a burnt smell, consider a fluid change.

3. Inspect Gear Shift Assembly

Remove interior trim panels surrounding the gear shift lever using a trim removal tool.
Check for any loose connections or damaged components within the gear shift assembly.
If damaged, replace the assembly with a new one.

4. Test Brake Switch

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

5. Examine Transmission Linkage

Raise the vehicle safely using a jack and secure with jack stands.
Locate the transmission linkage connected to the transmission.
Inspect for misalignment or wear. Adjust or replace as necessary.

6. Address Fluid Leaks

Identify and clean any areas where fluid is leaking.
Replace any damaged seals or gaskets to prevent further leaks.
