Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather tools such as a socket set, rags, and transmission fluid.

2. Clean the Area

Use rags to clean the transmission pan and surrounding areas of any old fluid or debris.
This will help identify new leaks more easily.

3. Inspect the Transmission Pan

Using a socket set, remove the bolts securing the transmission pan.
Carefully lower the pan; inspect the gasket for wear, and replace it if damaged.
Check for any cracks or damage to the pan itself; replace if necessary.

4. Replace Seals and Gaskets

If any seals or gaskets were found to be leaking, replace them with new ones.
Ensure that the surfaces are clean before applying any new gasket material.

5. Reassemble

Reattach the transmission pan using the appropriate torque specifications for the bolts (refer to the vehicle's service manual for exact values).
Refill the transmission fluid to the correct level as indicated on the dipstick.
