How Many Variations of the 4R100 / E4OD?

There are many different variations (so we have over 60 different part numbers!). Each one for a different engine size (bellhousing) and varying electronic and solenoid systems for different years.

Only certain models will interchange with others, which is why we ask for your 17-digit VIN# when you order so we are 100% sure it is the matching unit for your vehicle!

The E4OD was updated in 1998 and this new transmission was the last rendition of the C6. It was largely the same as the E4OD, but with some changes to internal components to address durability concerns when put behind the ever increasingly powerful Powerstroke Diesel Engine.

In 1999 it was fitted with a PTO (Power Take Off) 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.
