Solution

1. Preparation

Tools Required: Socket set, torque wrench, transmission fluid dipstick, UV dye kit (if necessary), safety goggles, gloves.
Safety Warnings: Ensure the vehicle is on a flat surface and secured with wheel chocks. Disconnect the battery before working on electrical components.

2. Inspect and Replace Seals

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the transmission pan by loosening the bolts with a socket wrench. Ensure to catch any fluid that may spill.
3. Inspect the gasket and seals for wear; replace them if they show any signs of damage.
4. Clean the mating surfaces of the transmission and pan.
5. Apply a new gasket or sealant as necessary, and reinstall the pan using a torque wrench to tighten the bolts to the manufacturer's specifications (usually around 10-12 ft-lbs).

3. Repair Fluid Lines

Sub-steps:
1. Locate the fluid lines connected to the transmission.
2. Check for any signs of damage or wear; if cracks or leaks are found, replace the affected line.
3. Disconnect the damaged line using the appropriate tools, and install the new line, ensuring that all connections are secure.
4. Refill the transmission fluid through the dipstick tube, ensuring to use the specified type of fluid (typically Mercon LV for Ford transmissions).

4. Final Inspection

Sub-steps:
1. Start the engine and let it idle while monitoring for any leaks around the transmission pan and fluid lines.
2. Shift through all gears to circulate the fluid and check for any slipping.
3. Recheck the fluid level after the engine warms up and add fluid as necessary.
