Ford F250 Automobile User Manual


 
Correct fluid level
The transmission fluid should be checked at normal operating
temperature 66°C-77°C (150°F-170°F) on a level surface. The normal
operating temperature can be reached after approximately 30 km (20
miles) of driving.
You can check the fluid without driving if the ambient temperature is
above 10°C (50°F). However, if fluid is added at this time, an overfill
condition could result when the vehicle reaches normal operating
temperature.
The transmission fluid should be in
this range if at normal operating
temperature (66°C-77°C
[150°F-170°F]).
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.
