Which is better, NV5600 or G56?
Im looking to get another Cummins in the next week or so and had some questions about the 6 speed. Ive had my 2000 since '04 and the NV4500 seems bullet proof (knock on wood). Ive found one 2007 with the 6.7 which i believe has the G56. Another one is an '05 with the nv5600. Which one would be best? Is one prone to failures? The truck will not get bombed too much. Just the basics and if i get the 6.7 all the EGR stuff is coming off since it wont ever have to pass emissions. By basics i mean intakes, full exhaust, and probably an edge module. Just looking for everyones 2 cents.

what HE said...the g56 has an aluminum case. the benefit is weight reduction, while the deficit it a compromise of strength. the torque load will have a more noticable impact on aluminum than it will on iron. the getrag was a fine trans for a 'vette, but the cummins can make short work of it due to the weight being moved, and the torque involved. they're both good though. my preference is the 5600.

Once the NV5600 is broken in, they shift like butter!!!!
