To give you the most accurate capacity and part number, could you tell me: What is the of your F-250?

Note: Some 2023+ models may require Mercon ULV; check your dipstick. Use Mercon LV . Ford superseded Mercon SP with LV for these years. 1997 – 2002 (4R100 Transmission): Use Mercon V .

Check the "Capacities and Specifications" section in the back of your manual.

Which does it have (e.g., 6.2L Gas, 6.7L PowerStroke)? Are you doing a simple drain or a full system flush ?

💡 Never mix different types of Mercon. While "LV" stands for Low Viscosity, it is not interchangeable with "V" or "ULV" unless specifically noted by Ford for your model year.

Use Mercon V (originally Mercon). 📍 How to Verify Your Fluid Type
