So I originally had a 47RE, and I bought a NV4500. My plan was to buy the Billet 1-3/8 Input Shaft, a Valair or Southbend double disk clutch, and bolt a NV271 T-Case to it. I use my truck for daily driving everyday with most my miles being city. I tow occasionally and I take it off road a lot through rocks or what ever I can clear, or maybe at some point sled pulling.
Now I am second guessing if I want the NV5600 or ZF-6. I know the real only difference is the extra gear of 3 and 4 in the 6 speeds. I would still bolt a NV271 T-case up to it. But I don't want to be in that situation if I ever do have to tow something around 20,000 lbs and struggle in that rare instance. My truck is not very modded yet but my goals are 500+ HP for it.
I also don't know if there is an upgraded input shaft for the NV5600 since it is already a 1-3/8. Is there anything I should upgrade for either transmission I have left out? I want something that can handle 500+ HP with out a doubt and be reliable.
Which transmission should I drop in?? It's making me go crazy!
I just want the most reliable transmission that can handle 500+ Hp...
