Solution

1. Preparation

Tools Required: Funnel, clean cloth, gloves.
Make sure the vehicle is parked on a level surface and the engine is running to allow the fluid to circulate.

2. Check Fluid Level

Remove the transmission dipstick again.
Wipe it clean with a cloth, then reinsert it completely.
Remove it once more to check the fluid level; it should be within the "Full" range on the dipstick.

3. Add Transmission Fluid

Tools Required: Funnel, new transmission fluid (Ford Mercon LV).
If the fluid is low, use a funnel to add the recommended transmission fluid through the dipstick tube.
Add fluid in small increments, checking the level frequently until it reaches the "Full" mark.

4. Inspect Fluid Condition

If the fluid is dark or has a burnt smell, consider a transmission fluid change rather than just topping it off.
Use a clean cloth to check for any metal shavings or contaminants on the dipstick.

5. Final Check

Reinsert the dipstick and ensure it is secured properly.
Close the hood and start the vehicle, allowing it to run for a few minutes.
Shift through all gears and check for smooth operation.
