Maintenance and Specifications The transmission fluid should be in this range if at ambient temperature (10°C-35°C [50°F-95°F]). High fluid level Fluid levels above the safe range may result in transmission failure. An overfill condition of transmission fluid may cause shift and/or engagement concerns and/or possible damage. High fluid levels can be caused by an overheating condition. Adjusting automatic transmission fluid levels Before adding any fluid, make sure the correct type is used. The type of fluid used is normally indicated on the dipstick and also in the Lubricant specifications section in this chapter. Use of a non-approved automatic transmission fluid may cause internal transmission component damage. If necessary, add fluid in 250 ml (1/2 pint) increments through the filler tube until the level is correct. If an overfill occurs, excess fluid should be removed by a qualified technician. An overfill condition of transmission fluid may cause shift and/or engagement concerns and/or possible damage. Do not use supplemental transmission fluid additives, treatments or cleaning agents. The use of these materials may affect transmission operation and result in damage to internal transmission components. 202 2004 04- Mustang (mus) Owners Guide (post-2002-fmt) USA English (fus)
