Quick answer
2017 owner's manual: Motorcraft MERCON ULV for the 3.5L EcoBoost; Motorcraft MERCON LV for the 2.7L EcoBoost, 3.5L and 5.0L. Other years: confirm for your engine in your owner's manual. Dipstick: Not confirmed for every year — see your owner's manual. The 2017 owner's manual says the automatic transmission does not have a transmission fluid dipstick.

How often should Ford F-150 transmission fluid be changed?+
The interval depends on your model year, transmission and how the vehicle is used, so we do not publish a single number for the Ford F-150. Your owner's manual or maintenance schedule gives the interval, usually with a shorter one for severe service such as towing, extreme heat or stop-and-go driving.
