1Use 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.2Add the coolant type originally equipped in your vehicle.3Your 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.4Service refill capacity is determined by filling the axle to 1/4-9/16 inch (6-14 mm) below the
bottom of the filler hole with the vehicle on a level surface.
Add 4 oz. (118 ml) of Additive Friction Modifier or equivalent meeting Ford specification
EST-M2C118-A, for complete fill of 9.75 inch Traction-Lok axles.5Approximate 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.6Automatic transmissions that require MERCONV should only use MERCONV fluid or fluid that
is specified dual usage MERCON/MERCONV. Use of any fluid other than the recommended fluid
may cause transmission damage. Refer toscheduled maintenance informationto determine the
correct service interval. Use of any fluid other than the recommended fluid may cause transmission
damage.7Service refill capacity is determined by filling the transfer case to the bottom of the filler hole
with the vehicle on a level surface.
