You've got 47RE and you want to put in a NV5600. not really a problem. you need the whole clutch assembly, peddle and steering column to make it look factory.
1st check your current tranny crossmember. if its the wide one (IE a foot wide with 2 different bolt patterns on it. you don't have to change it. the 5600 will use the rear most pattern. if you have the skinny crossmember you will have to change it.
the nv5600 has a 1 1/2" 29 spline output, I can't recall what the automatics are. you may have to find the correct input for the tcase. or get the tcase with the 5600.
the 5600 uses a 13" clutch. you have to get the correct flywheel for the 13" clutch. you might need a 3/4" spacer under the starter. I can't recall the reason right off the top of my head for that. but you might need it.
the NV5600 came with 2 different input shafts. the early 5600 was a 1 1/4" with 12 spline the "factory update" was 1 3/8" 10 spline input. 99-2000ish was the early 5600. you don't want one of those. you want the 1 3/8" 10 spline input. make sure that's what it is. if its the small one. you dont want it. because you get to choose right now, make sure its the big input to save any hassle/breakage in the future.
