4Visteon Traction-Lok axles require 4 oz. (118 ml) of Additive Friction
Modifier XL—3 or equivalent. Dana limited-slip axles (E250/350/450/550)
require 8 oz. (237ml) of Additive Friction Modifier XL—3 or equivalent

5Optional fuel tank 208L (55 gallon).6Ensure the correct automatic transmission fluid is used. Transmission
fluid requirements are indicated on the dipstick or on the dipstick
handle. Check the container to verify the fluid being added is of the
correct type. Refer to yourScheduled Maintenance Guideto determine
the correct service interval.
Some transmission fluids may be labeled as dual usage, such as
MERCONand MERCONV. These dual usage fluids are not to be used
in an automatic transmission that requires use of the MERCONtype
fluid. However, these dual usage fluids may be used in transmissions that
require the MERCONV type fluid.
MERCON, MERCONV and MERCONSP are not
interchangeable. DO NOT mix MERCON, MERCONV and
MERCONSP. Use of dual usage fluids in an automatic
transmission application requiring MERCONSP may cause
transmission damage. Use of a transmission fluid other than the
recommended fluid may cause transmission damage.
7Indicates only approximate dry-fill capacity. Some applications may vary
based on cooler size, if equipped with an in-tank cooler, if equipped an
oil to air cooler and if equipped with a remote filter assembly. The
amount of transmission fluid and fluid level should be set by the
indication on the dipstick’s normal operating range.
8If your vehicle is equipped with a single row radiator, there will be a
label on the top side of the radiator indicating “1 Row Radiator”.
9Use of synthetic or synthetic blend motor oil is not mandatory. Engine
oil need only meet the requirements of Ford specification
WSS-M2C930-A and the API Certification mark.
