Solution

1. Preparation

Tools Required:
- Socket set
- Torque wrench
- Screwdrivers
- Transmission jack (if necessary)
- Oil catch pan
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues during repairs.

2. Remove Transmission Fluid

Position the oil catch pan under the transmission.
Remove the drain plug (if equipped) or detach the transmission pan to drain the fluid.
Allow all fluid to drain completely before proceeding.

3. Inspect and Replace Seals

Inspect the Transmission Pan:
- Remove the bolts securing the transmission pan using a socket set.
- Carefully pry the pan off without damaging the gasket surface.
Replace Gasket and Seals:
- Clean the old gasket material from the pan and transmission surface.
- Install a new gasket and inspect or replace any damaged seals around the transmission.

4. Reinstall Transmission Pan

Align the transmission pan back onto the transmission.
Torque the pan bolts to manufacturer specifications (typically around 10-12 ft-lbs, but verify with service manual).
Reattach the drain plug (if applicable).

5. Refill Transmission Fluid

Using a funnel, refill the transmission with the appropriate type and amount of fluid as specified in the owner’s manual (usually Mercon LV for Ford vehicles).
Start the engine and let it run for a few minutes, shifting through all gears to circulate the fluid.

6. Final Check

Check the transmission fluid level again with the dipstick and add fluid if necessary to reach the proper level.
Inspect for any leaks around the pan and seals once the engine is running.
