Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface, engage the parking brake, and disconnect the battery.

2. Fluid Check and Replacement

Fluid Level Check
- Locate the transmission dipstick (if applicable) and remove it.
- Wipe clean, reinsert, then remove to check fluid level.
Fluid Replacement
- If fluid is low or degraded, drain the old fluid into a suitable container by removing the drain plug.
- Replace the drain plug and refill with the recommended transmission fluid (Toyota ATF WS) using a funnel until it reaches the proper level.

3. Inspect and Adjust Linkage

Locate the transmission linkage under the vehicle.
Inspect all connections for wear or damage; replace any faulty components.
Adjust the linkage according to the manufacturer specifications, ensuring it engages properly with the transmission.

4. Solenoid Testing and Replacement

Disconnect the wiring harness from the transmission solenoids.
Use a multimeter to check for resistance; refer to service manual for specific values.
If solenoids are faulty, remove and replace them following the service manual instructions.

5. Final Assembly and Testing

Reconnect all components and ensure the battery is reconnected.
Start the engine and allow it to warm up.
Test drive the vehicle to ensure the transmission shifts smoothly through all gears.
