Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Fluid Change

Sub-steps:
1. Remove the transmission pan by unscrewing the bolts (use a socket set).
2. Drain the old transmission fluid into a suitable container.
3. Clean the transmission pan thoroughly and inspect for metal shavings.
4. Replace the transmission filter (remove old filter, install new one securely).
5. Reinstall the transmission pan with a new gasket, tightening bolts to the specified torque (typically 7-9 ft-lbs).

3. Fluid Level Adjustment

Sub-steps:
1. Refill the transmission with the correct type of fluid (Toyota ATF WS).
2. Start the engine and let it warm up to normal operating temperature.
3. Shift through all gears and check the fluid level again, adding fluid as necessary.

4. Solenoid and Electrical Check

Sub-steps:
1. Reconnect the battery terminal.
2. Access the transmission control solenoids.
3. Test resistance with a multimeter; replace any solenoids showing out-of-spec readings.
4. Reassemble any covers or components removed during access.
