Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface with the engine off and cooled down.

2. Inspect Transmission Pan

Remove the transmission pan bolts using a socket set.
Carefully lower the pan to avoid spillage and inspect the gasket for any signs of wear or damage.
Clean the pan and replace the gasket if necessary.
Reinstall the pan with the correct torque (typically 10-12 ft-lbs) for the bolts.

3. Replace Transmission Cooler Lines

If leaks are found in the cooler lines, use a wrench to disconnect the lines from the transmission and radiator.
Replace the lines with new ones, ensuring proper fitting and sealing.
Reconnect the lines and tighten securely to prevent leaks.

4. Seal Replacement

If a seal is leaking, identify the specific seal (input or output) that requires replacement.
Use a seal puller to remove the old seal carefully.
Lubricate the new seal with fresh transmission fluid and install it using a seal driver or appropriate tool to ensure it sits evenly.

5. Fluid Top-Up

After repairs, check the fluid level using the dipstick.
Add the appropriate type of transmission fluid (usually Toyota Type T-IV or equivalent) as needed to achieve the correct level.
