Solution

1. Preparation

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

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the fluid level.
If low, add the appropriate type of transmission fluid (Toyota ATF WS) until it reaches the correct level.

3. Inspect and Repair Leaks

Identify any leaks around the transmission pan, seals, or hoses.
If leaks are found, replace the faulty seals or gaskets.
Clean any spilled fluid and ensure all connections are secure.

4. Test Transmission Control Module (TCM)

Locate the TCM, usually found near the transmission or under the dashboard.
Use a multimeter to check for proper voltage and ground connections.
If faulty, replace the TCM with a compatible unit.

5. Reassemble and Check Gear Linkage

Inspect the gear linkage for any signs of wear or damage.
Tighten or replace linkage components as necessary.
Reattach the gear shifter and ensure it engages correctly.

6. Final Check

Reconnect the negative battery terminal.
Start the engine and attempt to shift through all gears.
Monitor for any unusual noises or warning lights.
