Solution

1. Preparation

Gather tools: funnel, clean rags, and transmission fluid specific to Ford specifications.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Adding Transmission Fluid

Locate the Transmission Dipstick: Open the hood and locate the transmission dipstick, typically found near the back of the engine.
Remove the Dipstick: Pull the dipstick out and wipe it clean with a rag.
Check Fluid Level Again: Reinsert the dipstick, remove it again, and check the fluid level.
Add Fluid if Necessary: Using a funnel, add the appropriate type of transmission fluid through the dipstick tube. Add in small increments, checking the level frequently to avoid overfilling.
Replace the Dipstick: Once the desired level is reached, securely replace the dipstick.

3. Test Drive

Start the vehicle and allow it to warm up for a few minutes.
Shift through all gears to circulate the fluid, then check the fluid level again, topping off if necessary.
