Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe it clean, reinsert, and remove again to check fluid level.
If low, add the manufacturer-recommended transmission fluid until it reaches the correct level.

3. Inspect Gear Shift Linkage

Locate the gear shift linkage under the vehicle.
Visually inspect for any signs of wear, damage, or misalignment.
If damaged, remove the linkage by unbolting it and replacing it with a new part.

4. Test Brake Switch

Locate the brake light switch near the brake pedal.
Use a multimeter to test for continuity when the brake pedal is pressed.
If defective, disconnect the wiring harness and replace the switch.

5. Inspect Transmission Control Module (TCM)

Locate the TCM, typically found near the transmission.
Check the wiring harness for any corrosion or loose connections.
If necessary, clean the connectors or replace the TCM if it is malfunctioning.
