Solution

1. Preparation

Ensure the vehicle is parked on a level surface with the engine running.
Wear gloves to protect your hands from transmission fluid.

2. Check Fluid Level

Step 1: Locate the transmission dipstick. It is typically at the rear of the engine bay and marked with a yellow handle.
Step 2: Pull the dipstick out carefully and wipe it clean with a lint-free cloth to remove any fluid.
Step 3: Reinsert the dipstick fully into the tube, ensuring it is seated correctly.
Step 4: Remove the dipstick again and check the fluid level. The fluid should be between the "Full" and "Add" marks on the dipstick.
Step 5: If the fluid level is low, proceed to add transmission fluid.

3. Add Transmission Fluid (if necessary)

Step 1: Use a funnel to avoid spills and insert it into the dipstick tube.
Step 2: Add the recommended transmission fluid type (usually Mercon LV for Ford F-150) in small increments, checking the level frequently.
Step 3: Repeat the dipstick checking process to ensure the correct fluid level is achieved.
Step 4: Once the level is correct, remove the funnel and securely reinsert the dipstick.
