   No it comes from a C-6 as I have one apart here and I have Ross gearbox sitting here with a 4.4 ring gear in it but I have not seen a E4OD trans apart so it must be different than the early standard C-6

Ummm,  4.4"  sounds more like the C4 transmission offered
in the Falcon, Fairlane, and Mustang lines.
