1Add 8 oz. (236 ml) of Additive Friction Modifier XL-3 or equivalent meeting Ford Specification
EST-M2C118–A for complete refill of limited slip Ford axles. Ford design rear axles contain a
synthetic lubricant that does not require changing unless the axle has been submerged in water.
2Add the coolant type originally equipped in your vehicle.
3Ensure the correct automatic transmission fluid is used. Transmission fluid requirements are
indicated on the dipstick blade or the dipstick handle. Check the container to verify the fluid being
added is of the correct type. Refer to your scheduled maintenance information to determine the
correct service interval.
Automatic transmissions that require MERCON  LV should only use MERCON  LV fluid.
Use of any fluid other than the recommended fluid may cause transmission damage.
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.
5Use 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.
6Refer to Checking automatic transmission fluid in this chapter for the correct dipstick type.
Fill to the proper capacity according to dipstick Type A.
7Refer to Checking automatic transmission fluid in this chapter for the correct dipstick type.

Be sure to ask your dealership service advisor or technician about the
multi-point vehicle inspection. It’s a comprehensive way to perform a
thorough inspection of your vehicle. It’s your checklist that gives you
immediate feedback on the overall condition of your vehicle. You’ll know
what’s been checked, what’s okay, as well as those things that may
require future or immediate attention. The multi-point vehicle inspection
is one more way to keep your vehicle running great!Scheduled Maintenance
