The article deals with swapping to the AOD, a non-computer controlled transmission about the size of a C4 automatic.

The E4OD is as big as a house and is electronically controlled, requiring a controller either from the engine computer or a stand-alone unit.

Two very different animals.

If you have a 300, 302 or 351w, the AOD, properly beefed from an '88-'93 core would be the way to go.
