Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to avoid any electrical issues during repair.

2. Check and Top Off Brake Fluid

Locate the brake fluid reservoir.
Remove the cap and check the fluid level; top off with manufacturer-approved brake fluid if low.
Reconnect the battery and test if the gear shifter is now operational.

3. Inspect and Replace Brake Pedal Switch

Locate the brake pedal switch under the dashboard near the brake pedal.
Disconnect the wiring harness from the switch.
Remove the switch by unscrewing or unclipping it from its mount.
Install a new brake pedal switch by reversing the removal steps.
Reconnect the wiring harness and test the shift lever operation.

4. Inspect Shift Cable/Linkage

Access the shift cable/linkage by removing the center console or cover (if applicable).
Check for signs of wear, disconnection, or damage to the cable.
If damaged, replace the shift cable by detaching it from both the shift lever and transmission linkage.
Reinstall the new shift cable ensuring proper adjustment.

5. Check Transmission Fluid

Locate the transmission dipstick/filler cap (if accessible).
Remove the dipstick and check the fluid level and condition; fluid should be clean and at the appropriate level.
If low, add the correct type of transmission fluid as specified in the owner's manual.
If the fluid is dirty, consider performing a transmission fluid change.
