Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and engage the parking brake.
  • Disconnect the negative battery terminal to prevent electrical issues.
2. Check and Replace Transmission Fluid
  1. Remove the dipstick and wipe it clean.
  2. Insert the dipstick back into the tube and remove it again to check the fluid level.
  3. If low, add the manufacturer-recommended transmission fluid (Toyota ATF WS).
  4. If the fluid is burnt or discolored, drain the old fluid:
    • Place a drain pan under the transmission pan.
    • Remove the transmission pan bolts using a socket set.
    • Carefully lower the pan and allow the fluid to drain completely.
  5. Replace the old filter if applicable, using a new filter that meets OEM specifications.
3. Inspect and Replace Transmission Components
  1. If the fluid was contaminated, inspect internal components:
    • Remove the transmission pan for access.
    • Check for metal shavings or debris and clean thoroughly.
    • Inspect the valve body and solenoids for wear or failure.
  2. If solenoids are faulty, replace them:
    • Remove the electrical connectors.
    • Unscrew the solenoid from the valve body.
    • Install the new solenoid and reconnect electrical connectors.
4. Reassemble and Refill Fluids
  1. Reinstall the transmission pan with a new gasket, ensuring proper alignment.
  2. Torque the pan bolts to the manufacturer’s specifications (typically 8-10 ft-lbs).
  3. Refill the transmission with the correct type and amount of fluid.
  4. Reconnect the negative battery terminal.
