Ford F-150 Transmission Fluid

The correct transmission fluid for the Ford F-150, how much it takes, how often to change it, and how to check the level.

Quick answer

The Ford F-150 typically uses Motorcraft Mercon ULV (older 6-speed 6R80 used Mercon LV). Refill capacity on a drain-and-fill is ≈ 6 qt on a pan drop; ≈ 12.7 qt total, with a common change interval of ~150,000 mi normal; ~30,000–60,000 mi severe / towing. Dipstick: No. 2017+ F-150s use Mercon ULV in the 10R80 and are checked at a fill plug — confirm ULV vs LV for your model year.
