Lunched 7 NV4500's in my time driving Cummins trucks, 3 of them were rebuilt with the 5th gear fix. I will never own another Dodge with an NV4500. I have never tried an NV5600 6-speed to see how I could break one of those, but I might try someday...LOL

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
