AMSOIL Transmission Fluid for Ford Super Duty
Match transmission fluid to the exact Ford Super Duty transmission and service requirements.
Transmission fluid must match the transmission
Ford Super Duty trucks have used several automatic and manual transmissions. Do not select fluid based only on the truck badge or engine. Identify the transmission and required specification first.

Frequently asked questions
Which AMSOIL transmission fluid fits my Ford Super Duty?
It depends on the transmission and model year. Use AMSOIL’s vehicle lookup and verify the required specification before ordering.
Is transmission fluid especially important for towing?
Towing raises drivetrain load and heat. Correct fluid and manufacturer-recommended service intervals are important for transmissions used under heavy service.
Transmission fluid works hard in a tow vehicle
Automatic transmission fluid lubricates, cools and provides the hydraulic medium the transmission uses to operate. Towing, mountain grades, hot weather and repeated low-speed maneuvering can increase heat, so correct fluid and proper level are essential.
Identify the transmission
Ford Super Duty trucks have used multiple transmission families over the years. Select fluid by the actual transmission and model year, not simply by the Power Stroke engine badge.
Temperature matters
Excessive heat can shorten fluid life. Cooling-system condition and proper fluid level are important when towing heavy.
Service method
Drain-and-fill, pan service and complete fluid exchange are different procedures. Follow the service method appropriate for the transmission and its condition.
Transmission service should fit the whole drivetrain
When preparing a truck for towing, also review differential fluid, transfer-case fluid where applicable, engine oil and cooling-system maintenance.
