The swap is the same as the one you already did, pretty much.
I would buy new solenoids and stuff.
If you replace the 2002 plug and solenoids with the old style that your eec wants, everything internal will work fine.
You can buy the old style plug and wires new from PATC, as well as all new stuff.
If you have one rebuilt, make sure they use the one piece teflon seals on the Direct shaft and Input shaft; that makes a huge difference in longevity.
If you're a detail-oriented neat freak who loves the smell of Mercon V, you can rebuild your own transmission.
If you use a 2003 tranny, look in the hole for a tailshaft gear; if it ain't there, it can't be fixed without taking it ALL the way apart. It's FILO.
BTW; this thread is a great 4R70W rebuild thread, they deserve mad props.
