Is the 4R70W a 3.8L or 5.0L?

You have your facts wrong- on many different levels. The 4R70W has never been behind a V6 Explorer. And it has been behind the 5.0L Explorer, but with the different bellhousing. And the 4.6L 02+ Explorers have the 5R55W’s. A 3.8 is NOT, despite the urban myth, a “chopped down” 5.0L.

What’s the difference between the AOD and the 4R70W?

The AODE/4R70W is different because there is one input shaft instead of both a primary and intermediate shaft. The AODE/4R70W manual shift mechanism is basically the same as the AOD except it has no linear backup light/neutral safety switch.
