Solution

1. Preparation

Tools Required: Lint-free cloth or paper towel, funnel (if adding fluid).
Ensure the vehicle is on a level surface and the engine is warmed up.

2. Check Fluid Level

Remove the dipstick and observe the fluid on the tip.
The fluid should be within the marked range on the dipstick (typically "Full" and "Add" marks).
If the fluid level is low, proceed to add fluid.

3. Add Transmission Fluid (if necessary)

Tools Required: Funnel.
Use the correct type of transmission fluid specified in the owner’s manual (e.g., Ford Mercon LV).
Insert a funnel into the dipstick tube and add fluid slowly, checking the level frequently to avoid overfilling.

4. Recheck Fluid Level

After adding fluid, recheck the fluid level on the dipstick to ensure it is at the appropriate mark.
Replace the dipstick securely back into the tube.
