Most of the internals are the same, but not all. There are some sensors on the 4R100 that aren't on the E4OD, so it would follow that the tone rings or whatever the sensor feeds off of wouldn't be there in the earlier transmission. PLUS, a lot of components in the E4OD were aluminum that were upgraded to steel in the later 4R100s. I wouldn't want to go backwards on reliability by putting in the weaker components.
