Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

Tools Required: Dipstick (if applicable), funnel.
Remove the transmission dipstick, wipe it clean, and reinsert to check fluid level.
If low, add the correct type of transmission fluid as specified in the owner’s manual.
Inspect the fluid for burnt smell or dark color; if contaminated, the transmission fluid will need to be replaced.

3. Inspect Transmission Linkage

Tools Required: Socket set, screwdrivers.
Locate the transmission linkage and visually inspect it for any signs of wear or disconnection.
Tighten any loose bolts or screws, and replace any damaged linkage components.

4. Brake Switch Inspection

Tools Required: Multimeter, socket set.
Locate the brake switch near the brake pedal.
Use a multimeter to test the switch for continuity; replace if defective.
Ensure the brake lights function correctly, as this can affect gear engagement.

5. Electrical Diagnosis

Tools Required: Multimeter, wiring diagram.
Inspect all wiring and connectors related to the transmission control module for any signs of corrosion or damage.
Check the battery voltage; it should be between 12.4V and 12.7V. If low, charge or replace the battery.
