Solution

1. Preparation

Gather Tools and Parts:
- Funnel
- Clean rag
- Transmission fluid (specifically designed for Ford vehicles, typically Mercon LV)
Safety Precautions:
- Ensure the vehicle is parked on a level surface.
- Engage the parking brake.

2. Check Transmission Fluid Level

Start the engine and let it run for a few minutes to warm up the fluid.
Shift through all gears and return to "Park."
Pull the dipstick again to check the fluid level. If low, proceed to refill.

3. Refill Transmission Fluid

Insert a funnel into the dipstick tube.
Pour the appropriate transmission fluid slowly into the funnel, checking the level frequently to avoid overfilling.
Add fluid until the level reaches the "Full" mark on the dipstick.

4. Final Checks

Remove the funnel and securely replace the dipstick.
Start the engine again and let it run for a couple of minutes.
Shift through all gears and check the fluid level once more, adding more fluid if needed.
