3. Remove it again to check fluid level; add transmission fluid if low.
4. If fluid is burnt or debris is present, consider a fluid change.
Tools Required: Funnel, transmission fluid (specify type per owner's manual).

3. Inspect Gear Shifter and Linkage

Sub-steps:
1. Remove the center console (if necessary) to access the gear shifter assembly.
2. Check for any foreign objects or debris around the shifter.
3. Inspect the linkage for any signs of wear or disconnection; adjust or replace as needed.
Tools Required: Screwdrivers, socket set.

4. Replace Brake Light Switch (if faulty)

Sub-steps:
1. Locate the brake light switch near the brake pedal.
2. Disconnect the electrical connector and remove the switch.
