Solution

1. Preparation

Tools Required: Socket set, wrench set, transmission fluid pump, clean rags.
Safely lift the vehicle using jack stands and ensure it is secure.
Place a drain pan underneath the transmission to catch any fluid.

2. Identify the Source of the Leak

Sub-steps:
1. Clean the area around the transmission pan and lines with a degreaser to eliminate old fluid residue.
2. Start the engine and let it run until the transmission fluid reaches operating temperature.
3. Observe for leaks while the vehicle is running to pinpoint the exact location of the leak.

3. Repair the Leak

Sub-steps:
1. If the leak is from the transmission pan, remove the bolts using a socket wrench and carefully lower the pan.
2. Replace the transmission pan gasket with a new gasket.
3. If the leak is from the cooler lines, disconnect the lines using a wrench and replace them as necessary.
4. If the leak is from the seals, remove the transmission from the vehicle to access the seals and replace them accordingly.
5. Reinstall the transmission pan, ensuring all bolts are tightened to the manufacturer’s torque specifications (usually around 10-15 ft-lbs).
6. Fill the transmission with the appropriate type of transmission fluid (Toyota ATF WS).

4. Final Checks

Sub-steps:
1. Start the engine and let it run; check for leaks around the repaired areas.
2. Allow the vehicle to reach operating temperature and check the transmission fluid level again, adding fluid if necessary.
3. Take the vehicle for a short test drive, monitoring for any abnormal noises or shifting issues.
