So I’m trying to figure out wether my truck has a NV5600 or a NV4500 and I have no idea how to find out. I want to put a new dual clutch on but I was told I need to know the transmission first to know what clutch to get. I have a 24v 02 6speed. Please help!

Welcome... You have the NV5600.

I'm kinda surprised whomever clutch company you're talking to doesnt know that too. You might want to call Valair or Southbend as they're both very up to speed on what these trucks work best with. :thumbup:

nv4500 = 5 speed
nv5600 = 6 speed

5600 6 speed came with two different input shaft sizes, you have the larger one. 1 3/8 if I remember correct.
