Solution
1. Preparation
  • Gather tools and materials needed.
  • Ensure the vehicle is parked on a level surface and the engine is off.
2. Fluid Change
  • Drain Transmission Fluid:
    • Remove the transmission drain plug using a socket set.
    • Allow the fluid to fully drain into a suitable container.
  • Replace Filter:
    • Remove the transmission pan bolts and carefully detach the pan.
    • Replace the transmission filter with a new one as per manufacturer specifications.
3. Refill Transmission Fluid
  • Reinstall the Transmission Pan:
    • Clean the pan and install a new gasket.
    • Torque bolts to the manufacturer’s specifications (typically around 10-12 ft-lbs).
  • Add New Fluid:
    • Using a funnel, refill the transmission with the appropriate type and quantity of fluid (Toyota WS fluid recommended).
4. Check for Leaks
  • Start the engine and allow it to reach operating temperature.
  • Inspect for any leaks around the transmission pan and drain plug.
5. Test Drive
  • Conduct a test drive to ensure the transmission operates smoothly without slipping or harsh shifts.
