1Add the coolant type originally equipped in your vehicle.
2Fill 6 mm to 14 mm (1/4 inch to 9/16 inch) below bottom of fill hole.
Add 118 ml (4 oz.) of Additive Friction Modifier XL-3 or equivalent
meeting Ford specification EST-M2C118–A for complete refill of
Traction-Lok axles.
Your vehicle’s rear axle is filled with a synthetic rear axle lubricant and is
considered lubricated for life. These lubricants do not need to be
checked or changed unless a leak is suspected, service is required or the
axle assembly has been submerged in water. The axle lubricant should
be changed any time the rear axle has been submerged in water.
3Ensure 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 your scheduled maintenance guide to determine
the correct service interval.
Some transmission fluids may be labeled as dual usage, such as
MERCON
and MERCON
V. These dual usage fluids are not to be used
in an automatic transmission that requires use of the MERCON
type
fluid. However, these dual usage fluids may be used in transmissions that
require the MERCON
V type fluid.
MERCON
and MERCON
V type fluids are not interchangeable.
DO NOT mix MERCON
and MERCON
V. Use of a transmission
fluid that indicates dual usage (MERCON
and MERCON
V) in
an automatic transmission application requiring MERCON
may
cause transmission damage. Use of any fluid other than the
recommended fluid may cause transmission damage.
4Approximate dry fill capacity including transmission fluid cooling
system, actual refill capacities will vary based on vehicle application and
transmission fluid cooling system (i.e. coolers size, cooling lines. auxiliary
cooler capacities). The amount of transmission fluid and fluid level
should be set by the indication on the dipstick’s normal operating range.
