FORD 2014 E-450 v.1 - Manual (Page 207)

Adjusting Automatic Transmission Fluid Levels
Note: Use of a non-approved automatic transmission fluid may cause
internal transmission component damage.
Note: An overfill condition of transmission fluid may cause shift and/or
engagement concerns and/or possible damage.
Note: 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.
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick. Refer to the Technical
Specifications table in the Capacities and Specifications chapter.
If necessary, add fluid in 1/2 pint (250 ml) increments through the filler
tube until the level is correct.
If an overfill occurs, excess fluid should be removed by an authorized
dealer.
