Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to avoid any electrical issues while working.

2. Locate the Leak

Sub-steps:
- Use a flashlight to inspect the transmission pan, lines, and seals.
- Clean the area around the suspected leak with a shop towel to ensure a clear view of the source.

3. Repair the Leak

Sub-steps:
- If the pan is leaking:
  1. Remove the transmission pan by unbolting it. Use a socket set.
  2. Clean the surface of the transmission and the pan thoroughly.
  3. Replace the pan gasket with a new one and reattach the pan with the specified torque settings (typically around 12-15 ft-lbs).
- If the seals are leaking:
  1. Remove the old seals using a seal puller.
  2. Clean the sealing surfaces.
  3. Install new seals, ensuring they are seated properly.
- If the lines are leaking:
  1. Loosen the fittings on the leaking line using a wrench.
  2. Replace the damaged line with a new one and tighten the fittings securely.

4. Refill Transmission Fluid

Sub-steps:
1. Reconnect the battery.
2. Using a funnel, refill the transmission with the manufacturer-recommended fluid type (typically Mercon LV for Ford).
3. Start the engine and let it idle, then cycle through the gears to circulate the fluid.
4. Check the fluid level again and add more if necessary.
