Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Check and Top Off Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe the dipstick clean and reinsert it to check the fluid level.
If low, add the appropriate type of transmission fluid (consult owner’s manual for specification).
Start the engine and allow it to warm up. Recheck fluid level and top off as necessary.

3. Inspect and Adjust Gear Shift Linkage

Remove any covers or panels obstructing access to the gear shift linkage.
Visually inspect the linkage for damage or misalignment.
If necessary, adjust the linkage per vehicle specifications or replace any damaged components.

4. Check and Replace Brake Light Switch (if faulty)

Locate the brake light switch, usually found near the brake pedal.
Disconnect the electrical connector and remove the switch.
Test the switch using a multimeter; replace if it does not function correctly.
Install the new switch and reconnect the electrical connector.

5. Inspect Transmission for Internal Issues

If the previous steps do not resolve the issue, consider checking for internal transmission problems.
This may require dropping the transmission pan and inspecting the components, which may involve professional assistance.
