Solution

1. Preparation

Gather all necessary tools and parts before starting the repair.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues during repair.

2. Identify and Repair the Leak

a. Locate the Leak Source

Use a flashlight to inspect the transmission area thoroughly.
Clean the area with a degreaser to remove old fluid and debris for better visibility.

b. Replace Damaged Seals or Lines

If the leak is from a line:
- Use a socket set to remove the affected line and replace it with a new one.
- Tighten connections to the manufacturer's torque specifications (usually around 12-15 ft-lbs).
If the leak is from a gasket:
- Remove the transmission pan by loosening the bolts with a socket wrench.
- Replace the old gasket with a new one, ensuring the mating surfaces are clean and smooth.
- Reinstall the pan and tighten bolts to the recommended torque (typically 8-10 ft-lbs).

3. Refill Transmission Fluid

Using a funnel, pour the correct type of transmission fluid (Toyota ATF WS) into the dipstick tube until the proper level is reached.
Start the engine and let it run for a few minutes, then check the fluid level again and add more if necessary.
