I would never own an NV4500 truck again, stranded too many times with the 5th gear issue and the last two times the trans had the "fix". Also had bad luck with a G56 Mercedes 6-speed, so the only manual I would own is an NV5600 6-speed.


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