Solution

1. Preparation

Gather the necessary tools and parts.
Raise the vehicle using a jack and secure it with jack stands.
Ensure the engine is off and cool to avoid burns.

2. Identify the Leak Source

Clean the area around the transmission pan and seals with a degreaser.
Use a UV light to check for the dye and identify the exact location of the leak.

3. Replace Damaged Seals or Gaskets

Transmission Pan Gasket Replacement
- Remove the transmission pan bolts with a socket wrench.
- Carefully lower the transmission pan and discard the old gasket.
- Clean the mating surface on both the pan and transmission.
- Install a new gasket and reattach the transmission pan, tightening the bolts to the manufacturer’s specified torque (typically around 12-15 ft-lbs).
Input/Output Shaft Seal Replacement
- Remove the necessary components (e.g., driveshaft or axles) to access the seals.
- Use a seal puller to remove the old seals.
- Apply a light coat of transmission fluid to the new seals and press them into place.

4. Refill Transmission Fluid

Locate the transmission fill plug and remove it.
Using a funnel, refill the transmission with the manufacturer-recommended fluid type (usually Mercon ULV for Ford).
Check fluid levels with the dipstick, adding more fluid as necessary.

5. Test for Leaks

Start the engine and allow it to reach operating temperature.
Shift through all gears to circulate the fluid.
Inspect the previously affected areas for any signs of leaks.
