Ekkk... Well I'm not a tranny type guy... But I'm sure there some saavy guys here that could help you out some how...

Here is about everything you will need to know as well as get parts. great company, well worth the few bucks you will spend to get quality info. The NV4500 and 5600 info has been closely gaurded as far as finding it online over the years. At best I have found some good pictures and thats about it. http://www.4x4repairmanuals.com/nv4500manuals.html

That should be very helpful...

Broke the outputshaft on one at work and rebuilt it, take your time, take pics if you need and lay everything out kind of in order. The website that wild and free posted is a great site for sure, I use this company for any tranny and gearing stuff because their only 45 minutes down the road from me. http://www.wadetransmission.com/ -Jordan-
