While it may bolt in the electronics is totally different. The trans from a 5.9 is a totally different animal then what is behind a 4.7 or a 5.7 so the electronics will not work. But you could use one from a 5.2 of about the same vintage. But remember that the 5.9 is externally balanced so you must use a converter for a 5.9 that will fit whatever trans you use

Do u have any recommendations I could use plz??
Didn't I just tell you? anything from behind a 4.7 or 5.7 will not work because of the electrical differences. A trans from a 5.9, 5.2 should work, and you want to risk it being too light one from a 3.9 would probably fit in too, but I would not recommend it and you most likely will not find a 5.9 converter for that. But you have to have a torque converter for a 5.9 or it will vibrate your teeth out. and for sure not before 1996, because they were not computer controlled.

And don't use the converter from the junk trans, there maybe metal filing in it from the old trans. I should of asked what is not working on the old trans, if it is just not shifting right it may not be the trans at all, could be wiring or computer or speed sensors.
if your tach or speedometer are not working then is not a transmission problem, that would be speed sensors or electrical. then get it scanned before you pull it out. it may not have to come out. if it is electrical replacing the trans is not going to fix it.
