Capacities and specifications Item Automatic transmission Windshield washer fluid 1 Ford part name or equivalent Motorcraft MERCON ATF 2 Ford part number XT-2-QDX Ford specification MERCON Ultra-clear Windshield Washer Concentrate C9AZ-19550-AC ESR-M17P5-A Add 236 ml (8 oz.) of Additive Friction Modifier C8AZ-19B546-A or equivalent meeting Ford specification EST-M2C118-A for complete refill of Traction-Lok 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 "Service Guide" for change intervals on Dana rear axles. 2 Ensure the correct automatic transmission fluid is used. Transmission fluid requirements are indicated on the dipstick or on the dipstick handle. Check the container to verify the fluid being added is of the correct type. Refer to your scheduled maintenance guide to determine the correct service interval. Some transmission fluids may be labeled as dual usage, such as MERCON and MERCON V. These dual usage fluids are not to be used in an automatic transmission that requires use of the MERCON type fluid. However, these dual usage fluids may be used in transmissions that require the MERCON V type fluid. MERCON and MERCON V type fluids are not interchangeable. DO NOT mix MERCON and MERCON V. Use of a transmission fluid that indicates dual usage (MERCON and MERCON V) in an automatic transmission application requiring MERCON may cause transmission damage. Use of any fluid other than the recommended fluid may cause transmission damage. 255
