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 Guide for change intervals on Dana rear axles. 2 Ensure the correct automatic transmission fluid is used. Transmission fluid requirements are indicated on the end of the dipstick. 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௡, 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. 290 2004 F250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA English (fus)
