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.3Service 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 XL-3 or equivalent meeting Ford specification EST-M2C118-A, for complete
fill of 8.8 inch and 9.75 inch Traction-Lok axles.4Service refill capacity is determined by filling the axle to the bottom of the filler hole with the vehicle on a level surface.
For 10.25 inch Traction-Lok axles, use 6.5 pints (3.1L) of Motorcraft SAE 75W-140 Synthetic Rear Axle Lubricant and 8 oz.
(236 ml) of Additive Friction Modifier XL–3 or equivalent meeting Ford Specification EST-M2C118-A.5Your 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.6Service refill capacity is determined by filling the transfer case to the bottom of the filler hole with the vehicle on a level
surface.7Approximate 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.8Automatic transmissions that require MERCONV should only use MERCONV fluid or fluid that is specified dual usage
MERCON/MERCONV. Refer toscheduled maintenance informationto determine the correct service interval. Use of
any fluid other than the recommended fluid may cause transmission damage.
