4Indicates only approximate dry-fill capacity. Some
applications may vary based on cooler size and if
equipped with an in-tank cooler. The amount of
transmission fluid and fluid level should be set by
the indication on the dipstick’s normal operating
range.
5Service refill capacity is determined by filling the
transmission to the bottom of the filler hole with the
vehicle on a level surface.
6Use of synthetic or synthetic blend motor oil is not
mandatory. Engine oil need only meet the
requirements of Ford specification WSS-M2C153–H
and the API Certification mark.
