Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and use wheel chocks for safety.
Disconnect the battery before beginning work to prevent electrical issues.

2. Drain and Remove Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set, starting at one corner.
Allow the old transmission fluid to drain completely into the pan.

3. Inspect and Replace Gasket or Seals

Remove the transmission pan completely after draining.
Inspect the old gasket for damage; if cracked or worn, replace it.
Clean the transmission pan mating surface thoroughly with a gasket scraper and solvent.
If seals are found to be leaking, replace the input/output shaft seals:
- Remove the old seals using a seal puller.
- Press in new seals using a seal driver.

4. Reinstall Transmission Pan

Place the new gasket onto the pan or the transmission surface.
Reinstall the transmission pan, ensuring it is aligned properly.
Torque the pan bolts to the manufacturer specifications (typically 8-12 ft-lbs).

5. Refill Transmission Fluid

Use a funnel to refill the transmission with the correct type and amount of fluid (refer to the owner's manual, typically Toyota ATF WS).
Start the engine and let it idle, then shift through all gears to circulate fluid.
Check the fluid level again and add more if necessary.
