Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface with the parking brake engaged.
  • Disconnect the battery to prevent electrical issues during service.
2. Fluid Inspection and Replacement
  • Fluid Level Check:
    • Remove the transmission dipstick and wipe it clean.
    • Reinsert the dipstick and remove it again to check fluid level.
    • If low, add the recommended type of transmission fluid (Toyota ATF WS).
  • Fluid Change:
    • Raise the vehicle and secure it with jack stands.
    • Locate the transmission fluid drain plug and place a pan underneath.
    • Remove the drain plug and allow fluid to drain completely.
  • Filter Replacement:
    • Remove the transmission pan by unscrewing the bolts using a socket set.
    • Carefully detach the pan and replace the transmission filter.
    • Clean the pan and reinstall it with a new gasket, torquing bolts to 8-10 ft-lbs.
3. Solenoid Testing and Replacement (if necessary)
  • Testing:
    • Disconnect the electrical connectors from the solenoids.
    • Use a multimeter to check for resistance per the manufacturer's specifications.
  • Replacement:
    • If any solenoid is faulty, remove it from the transmission.
    • Install the new solenoid in the same position and reconnect the wiring.
4. Final Checks
  • Reconnect the battery and start the vehicle.
  • Allow the engine to reach normal operating temperature.
  • Shift through all gears to ensure smooth operation.
