Nv4500 vs nv5600 which is better?

Just like it says I've been looking for awhile now and have decided that a 01 is what I'm getting but still don't know which is the better transmission

Depends on what you plan on doing with the truck. From what i've heard a 5600 is much more expensive to fix and parts are harder to come by. If you plan on towing ive heard the 56 is better because the gears are closer together. If you just want a manual go 4500. As long as you keep an eye on the 5th gear nut and the fluids its a nice stout transmission

It depends on what kind of towing and driving you want to do... The NV5600 is the workhorse trans that has tighter ratios (ending with the same final drive) than the NV4500. The gap between 3rd and 4th in my 4500 is considerable, so towing lots of weight uphill takes forethought on what gear you wanna be in/what point you need to shift, but nothing crazy. I've heard some guys with 5600s saying the 6 speed feels like a LOT of shifting around town unloaded, and parts are harder to find. I really don't think you could go wrong either way, so try and drive both and buy what you like.

I like my nv5600, but sometimes it doesnt like me. So thats when i jam a gear just a little harder to let it know who is still in charge.

I like the nv5600, driving around town unloaded is not that bad. Now with a 10k trailer that's a different story.
