Add 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 but do require a change.
Refer to your scheduled maintenance information for change intervals
on Dana rear axles.
2
Add the coolant type originally equipped in your vehicle.

Ensure the correct automatic transmission fluid is used. Transmission
fluid requirements are indicated on 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.
MERCON , MERCON V and MERCON SP are not
interchangeable. DO NOT mix MERCON , MERCON V and
MERCON SP. Use of dual usage fluids in an automatic
transmission application requiring MERCON SP may cause
transmission damage. Use of a transmission fluid other than the
recommended fluid may cause transmission damage.

Service refill capacity is determined by filling the transmission to the
bottom of the filler hole with the vehicle on a level surface. The 6–speed
manual transmission is equipped with an in-tank cooler. Verify the fluid
level after operating vehicle to ensure correct fluid level.
5
Indicates 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.
