Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.
Wear safety gloves and goggles.

2. Identify and Repair Leaking Component

A. Transmission Pan Gasket Replacement
- Remove the bolts securing the transmission pan using a socket set.
- Carefully lower the pan to avoid spilling fluid.
- Clean the mating surfaces of the transmission and pan thoroughly.
- Install a new gasket on the pan and reattach it, tightening bolts to the manufacturer’s specified torque (usually around 10-12 ft-lbs).
B. Replace Damaged Seals
- If the leak is from the input/output shaft seals, remove the driveshaft or axles as necessary.
- Use a seal puller to remove the old seals.
- Lubricate the new seals with transmission fluid and install them carefully.

3. Refill Transmission Fluid

Use a funnel to add the correct type of transmission fluid (check owner’s manual for specification) through the fill tube.
Start the engine and let it warm up, then check the fluid level again and add more if necessary.

4. Clean Up and Recheck

Clean any spilled fluid from the undercarriage and driveway.
Lower the vehicle and perform a test drive to verify the repair.
