I went through 7, YES 7, NV4500's in my 1999 Cummins diesel dually. Each time the nut came off I was hauling a 48" enclosed loaded and the damage was much more than just the nut coming off! The last two trans had the aftermarket fix, didn't due any good. eyes I will NEVER buy another NV4500, or G56 trans again in my life! tsk I haven't tried to ruin an NV5600 yet, but probably will sometime in my life... realcrazy

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