Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface.
Disconnect the battery to prevent any electrical issues during the repair.

2. Change Transmission Fluid

Tools Required: Socket set, funnel, transmission fluid pump.
Remove the transmission drain plug and allow the old fluid to completely drain into a suitable container.
Replace the drain plug and torque it to the manufacturer’s specifications (usually around 30 ft-lbs).
Using a funnel, refill the transmission with new fluid, adhering to the manufacturer's specifications (typically Toyota ATF WS fluid).
Start the engine and let it run for a few minutes, then check the fluid level again and top off as necessary.

3. Replace Transmission Filter

Tools Required: Socket set, screwdrivers, new transmission filter.
Remove the transmission pan by loosening the bolts with a socket wrench. Be cautious as fluid may still be present.
Once the pan is off, remove the old transmission filter by unfastening any retaining clips.
Install the new filter, ensuring it is seated properly.
Clean the transmission pan and replace the gasket before reattaching the pan, tightening the bolts to the specified torque.

4. Inspect and Replace Solenoids (if necessary)

Tools Required: Socket set, multimeter, replacement solenoids.
Locate the solenoids based on the vehicle’s service manual.
Disconnect the electrical connectors and remove the solenoids.
Test the solenoids with a multimeter to ensure they are within specifications; replace if faulty.
Reinstall the new or tested solenoids, reconnecting the electrical connectors securely.
