requirements of Ford specification WSS-M2C930-A and the API Certification mark.2Add the coolant type originally equipped in your vehicle.3Indicates 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.4Automatic transmissions that require MERCONV should only use MERCONV fluid. Refer to
scheduled maintenance informationto determine the correct service interval. Use of any fluid
other than the recommended fluid may cause transmission damage.5See your authorized dealer for fluid level checking or filling.
