I thought I read that some 4r70w parts can be used in a AOD to improve it,I have a 89 AOD that needs rebuilt and picked up a 4r70w along with a 302 today,

there's a big advantage to sticking with the 4r70w, assuming it'll bolt up to your engine.  a programmable controller for it costs about as much as a manual valve body.

to answer your question though, a 4r70w is basically a stronger/tougher aod with an electronic controller in lieu of the throttle valve...which means you can stuff 4r70w parts into an aod. 

overall, the electronic controller in the 4r70w can give you a lot more bang for the buck IMO.

I pulled the AOD from my LTD and put a 4R70W in it, with a baumann shift controller.  You can tailor shift points, shift firmness, converter lock up, and many other things, its a worthwhile change, glad I did it.
