Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Locate the Leak

Raise the vehicle with jack stands and secure it.
Clean the area around the transmission pan and components with degreaser to identify fresh leaks.

3. Replace Seals or Gaskets

If the leak is from the transmission pan:
- a. Remove the bolts securing the transmission pan using a socket set.
- b. Carefully lower the pan and drain the fluid into a container.
- c. Remove the old gasket and clean the mating surfaces.
- d. Install a new gasket, ensuring proper alignment.
- e. Reinstall the transmission pan, tightening bolts to the manufacturer's torque specifications (typically 8-10 ft-lbs).
If the leak is from the transmission input/output seal:
- a. Remove the driveshaft or axle if necessary to access the seal.
- b. Use a seal puller to remove the old seal.
- c. Apply a thin layer of transmission fluid to the new seal's lip and carefully press it into place.
- d. Reinstall the driveshaft or axle.

4. Replace Fluid

a. Refill the transmission with the appropriate type of fluid (Toyota Type T-IV or WS) using a funnel through the dipstick tube.
b. Start the engine and allow it to warm up, then shift through all gears to circulate the fluid.
c. Recheck the fluid level and add more if necessary.
