Maintenance and Specifications 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. 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. 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. 6 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. 3 289 2006 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus)
