1998 f150 4r70w Transmission and 2001 E350 4r70w

1998 F150 5.4 - is it 2WD or 4WD, and are you sure it has a 4R70W, not a E4OD?
2001 E-350 5.4 - assuming 2WD, are you sure it didn't come with a 4R100?
If they are both 2WD and both came with a 4R70W, they are interchangeable, but with some possible electronic differences. A 4WD transmission will not work in a 2WD vehicle because of different tailshaft housings. A 4R100 computer and wiring harness will not work on a 4R70W. An E4OD might work in place of a 4R100.
