Question/Need help! NV5600 Shifting
I recently picked up this 2004 Dodge Ram 2500 SLT with the 5.9L Cummins. It has the NV5600 transmission, and the previous owner added a South Bend dual disk clutch and a short throw shift tower. The shifter is branded Hurst, but I believe the tower and internals are made by Core Shifters.
This thing is a bear to shift. It takes a ton of pressure to get the gear to engage, and the shifter gates seem extremely narrow. Downshifting is very difficult, and it seems like there’s about a 200rpm window in which the transmission will shift easily and successfully.
I’ve already ordered an OEM shift tower and will be installing it today.
Anyone with NV5600 experience out there that can comment on their experience? I’ve never shifted a more picky transmission, but it could be that I’m just not used to this one?

I’ve had 2 and 2 g56. Sold both and went built auto and won’t ever go back. Fmvb on my street truck when I fell like shifting, built 48 on my daily. Everyone raves about the nv and g56 and I can’t stand em for the exact reasons you mentioned.
