Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Drain the Transmission Fluid

Tools Required: Drain pan, socket set, torque wrench.
Loosen and remove the transmission pan bolts using a socket.
Carefully lower the pan and allow the fluid to drain completely into the drain pan.
Clean the pan and magnet inside for metal shavings.

3. Replace Seals and Gaskets

Tools Required: Gasket scraper, seal puller.
Remove old transmission pan gasket and inspect for damage.
Replace any damaged seals, including the pan gasket and any input/output shaft seals.
Apply a thin layer of sealant if required by manufacturer specifications.

4. Reassemble and Refill

Reinstall the transmission pan and tighten bolts to the manufacturer’s torque specifications (usually around 10-12 ft-lbs).
Refill the transmission with the correct type of fluid (consult owner's manual for specifications, typically Toyota ATF WS).
Start the engine and let it run for a few minutes while checking for leaks.
