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 axles. Ford design rear axles contain a synthetic lubricant that does
not require changing unless the axle has been submerged in water. Dana
rear axles also contain a synthetic lubricant butdorequire a change.
Refer to yourScheduled Maintenance Guidefor change intervals on
Dana rear axles.
2Ensure the correct automatic transmission fluid is used. Transmission
fluid requirements are indicated on the end of the dipstick. Check the
container to verify the fluid being added is of the correct type. Refer to
yourScheduled Maintenance Guideto determine the correct service
interval.
MERCON, MERCONV and MERCONSP are not
interchangeable. DO NOT mix MERCON, MERCONV and
MERCONSP. Use of dual usage fluids in an automatic
transmission application requiring MERCONSP may cause
transmission damage. Use of a transmission fluid other than the
recommended fluid may cause transmission damage.
