'04/05 4t65e in a '98 GTP

Ok, what's the deal on swapping these trannies into a '98 GTP. I know the final drive will be different and I'll need the non-hd axle if I do this, but I've got a friend with one I can get pretty cheap. If I can swap the range switch and reprogram the gears via my powrtuner, will everything else plug and play, or do I need to do some custom wiring? Just tell me what needs to be done and I can probably do it.
 




Uh..guys. 03 the only year I was aware of being an issue beyond adding the range switch and dealing with the click style lines vs threaded.

I'd check with TEP and search. Pretty sure it's not a VB issue, check though...
