Solution

1. Preparation

Gather necessary tools: clean cloth, funnel (if needed), and a container for fluid if adding.
Safety warning: Ensure the engine is off and cool before starting the inspection if there is no dipstick.

2. Check Fluid Level with Dipstick

Remove the dipstick: Pull the dipstick out of the tube.
Wipe the dipstick: Use a clean cloth to wipe off any fluid.
Reinsert and remove: Push the dipstick back into the tube completely, then pull it out again to check the level.
Assess fluid level: The fluid should be between the "FULL" and "ADD" marks on the dipstick. If it's low, proceed to add fluid.

3. Adding Transmission Fluid (if necessary)

Choose the correct fluid: Use Ford-approved transmission fluid (e.g., Mercon LV for the S550).
Insert a funnel: Place a funnel into the dipstick tube or fill plug.
Add fluid: Pour the fluid slowly, checking the level frequently to avoid overfilling.
Recheck the level: After adding fluid, repeat the dipstick check to ensure the correct level is achieved.

4. Finalize

Replace the dipstick or fill plug: Ensure it is secured properly.
Clean up: Wipe any spills and dispose of any used fluids responsibly.
