Add 8 oz. (236 ml) of Additive Friction Modifier XL-3 or equivalent meeting Ford Specification

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 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.
4
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.

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.

Use 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.
