Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during repairs.

2. Locate and Repair the Leak

Inspect the Transmission Pan:
- Remove any undercarriage shields if applicable.
- Use a socket set to remove the bolts securing the transmission pan.
- Gently lower the pan and examine the gasket. If damaged, replace it.
Replace Transmission Fluid:
- Drain the old fluid into a suitable container.
- Replace the transmission fluid filter if applicable.
- Reinstall the transmission pan with a new gasket, torquing the bolts to the manufacturer's specifications (typically around 10-15 lb-ft).
Check and Replace Seals:
- Inspect the input and output shaft seals for wear.
- If leaking, remove the old seals using a seal puller and install new seals, ensuring they are seated correctly.

3. Refill Transmission Fluid

Using a funnel, refill the transmission with the recommended fluid type (usually Mercon LV for Ford vehicles).
Start the engine and allow it to reach operating temperature, then check the fluid level again, adding fluid as necessary.
