Diagnostic Steps

2
Start the engine and allow it to reach normal operating temperature.

Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is warmed up.
Gather necessary tools:
- Clean, lint-free cloth
- Funnel (if adding fluid)

2. Check Fluid Level

For Vehicles with a Dipstick:
1. Remove the dipstick from the transmission.
2. Insert the dipstick back into the tube without pushing it all the way down.
3. Remove the dipstick again and observe the fluid level; it should be between the "Full" and "Add" marks.
For Vehicles Without a Dipstick:
1. Remove the fill plug located on the transmission case.
2. Insert a finger or a clean straw into the fill hole.
3. If fluid is present at the edge of the hole, the level is adequate; if not, fluid needs to be added.

3. Add Transmission Fluid (if necessary)

If the fluid is low, use a funnel to add the manufacturer-recommended transmission fluid (typically Mercon LV for Ford).
Add fluid slowly, checking the level frequently to avoid overfilling.

4. Reinstall Dipstick or Fill Plug

Ensure the dipstick or fill plug is securely reinstalled after checking or adding fluid.
