Solution

1. Preparation

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

2. Check Transmission Fluid

Remove the transmission dipstick (if applicable) and wipe it clean.
Reinsert the dipstick and remove it again to check the fluid level.
If low, add the recommended type of transmission fluid (typically Toyota Type T-IV or WS).

3. Inspect for Fluid Leaks

Place a clean, dry surface under the transmission area.
Look for any signs of transmission fluid leaks.
If leaks are found, replace any damaged seals or gaskets.

4. Test Transmission Control Module (TCM)

Reconnect the battery and start the vehicle.
Use a multimeter to check the TCM's power and ground connections.
If faulty, replace the TCM following the manufacturer’s guidelines.

5. Inspect and Adjust Gear Linkage

Visually inspect the gear linkage for any signs of wear or damage.
Adjust or replace any affected components to ensure proper linkage alignment.
