Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shorts.
Ensure the vehicle is on a level surface with the parking brake engaged.

2. Inspect Brake Light Switch

Locate the brake light switch, usually mounted near the brake pedal.
Disconnect the electrical connector from the switch.
Use a multimeter to test the switch for continuity when the pedal is pressed.
- If the switch is faulty, replace it with a new one.

3. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check fluid level.
If low, add the appropriate type of transmission fluid as specified in the owner’s manual.
Inspect the fluid for burnt smell or debris; if contaminated, consider a transmission fluid change.

4. Inspect Gear Shift Linkage

Visually inspect the gear shift linkage for any damage or disconnection.
If the linkage is loose or damaged, replace or adjust it to ensure proper engagement.

5. Test Shift Interlock Solenoid

Locate the shift interlock solenoid, usually near the gear shift assembly.
Disconnect the electrical connector and test the solenoid with a multimeter.
- If it does not operate correctly, replace the solenoid.

6. Reassemble and Reconnect

Reconnect all electrical connectors and ensure all components are secured.
Reconnect the battery.
Perform a test by attempting to shift out of park again.
