Just wondering what transmission I have in my 04 Expedition EB with 4x4 and 5.4l engine. I see two listed: 4R100 & 4R70W. Anybody know what transmission was used?
I think I remember Ford going exclusively to th 70 version sometime around '04 or '05. Crawl under the truck and take a look. The 100 is big and boxy looking while the 70 has a more traditional bell shape (also smaller).
buzzard, Thanks for you input.
I have been searching since first posting. Most of my search leads me to the 70, but still not clear. Looking at the transmission I would say that it is more bell shaped, not boxy. I will continue my search, as well as looking for some kind of ID on the tranny.
