Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Place safety glasses and gloves on for protection.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Locate the Leak

Inspect the transmission pan and the surrounding area for signs of leakage.
If necessary, clean the area with a degreaser to identify the source of the leak more easily.

4. Repair or Replace Seals and Gaskets

If the leak is from the transmission pan gasket:
1. Remove the bolts securing the transmission pan.
2. Carefully lower the pan and discard the old gasket.
3. Clean the mating surfaces thoroughly.
4. Install a new gasket and reattach the pan, tightening bolts to specified torque (usually around 12-15 ft-lbs).
If the leak is from a seal:
1. Remove the component associated with the leaking seal (e.g., output shaft or input shaft).
2. Replace the old seal with a new one, ensuring it is seated properly.
3. Reinstall the component according to manufacturer specifications.

5. Refill Transmission Fluid

Refill the transmission with the appropriate type and amount of fluid as specified in the owner's manual.
Use a funnel to avoid spillage and check the fluid level with the dipstick.

6. Lower the Vehicle

Remove jack stands and carefully lower the vehicle back to the ground.
