some of which are air shifted. It is also widely used in off-road applications due to its reputation of being nearly indestructible. It does, however, have a reputation of greatly reducing performance as well as fuel mileage, due to the amount of power it requires to operate.

The E4OD was introduced in 1989 and used in both light and heavy duty applications. The E4OD has four forward speeds and electronic shift controls replacing the hydraulic governor control mechanism of the C6. The valve body was completely redesigned from the C6. The E4OD also has an additional planetary gear set to add 4th gear and a lockup clutch in the torque converter.

It was largely the same as the E4OD, but with some changes to internal components to address durability concerns when put behind increasingly powerful versions of the Powerstroke Diesel Engine. In 1999 it was fitted with a PTO for auxiliary equipment attached to heavy duty trucks. To follow Ford's new naming schemes for its other transmissions, Ford renamed the E4OD the 4R100.
