Solution

1. Preparation

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

2. Check Transmission Fluid

Tools Required: Transmission dipstick, funnel, new transmission fluid.
Remove the dipstick and check fluid level and condition (should be pink/red and not burnt).
If low, add the appropriate type of transmission fluid as specified in the owner's manual.
If fluid is dark or has debris, consider a fluid change.

3. Inspect Transmission Linkage

Tools Required: Socket set, wrenches.
Locate the linkage connecting the gear shifter to the transmission.
Inspect for any loose, disconnected, or damaged components.
Tighten or replace components as necessary.

4. Replace Brake Switch (if faulty)

Tools Required: Screwdriver, socket set.
Locate the brake light switch near the brake pedal.
Disconnect the wiring harness and remove the old switch.
Install the new brake switch and reconnect the wiring harness.

5. Reset Transmission Control Module (TCM)

Tools Required: OBD-II scanner.
Connect the OBD-II scanner to the vehicle's diagnostic port.
Follow the scanner instructions to clear any transmission error codes.
Disconnect the scanner and reconnect the battery.
