WJ 42re transmission

I have a friend with a smoked transmission in his 2002 WJ 4.0. We have found a 2004 WJ 42re but have been told the transmissions are internally different and that OD will not work properly from an '02 to an '04. Does anyone have any experience with this?

I don't have any direct experience with these but de remember there being a difference that does not allow them to interchange. Most likely to do with the electronics.
