1. Locate the transmission oil pan and remove the bolts using a socket set.
2. Carefully lower the pan and drain the old transmission fluid into a suitable container.
3. Clean the transmission pan and replace the filter if applicable.
4. Reinstall the pan with a new gasket and torque the bolts to the manufacturer's specifications (usually around 8-10 ft-lbs).
5. Refill the transmission with new fluid, ensuring the correct type (typically Toyota ATF WS).

3. Solenoid Replacement (if applicable)

Sub-steps:
1. Remove the transmission access cover to access the solenoids.
2. Disconnect the electrical connectors from the faulty solenoids.
3. Remove the solenoids from their mounting position.
