    go with a nv4500, they are tough, have a good low gear and overdrive. but they get a little expensive

    NV4500 and NV5600 come with the cummins. i have an NV5600 in my new truck. they are putting some in house built G56 in now, that would also bolt right up once adual mass flywheel was installed. that could take some work as i dont know if the crank bolt patern has changed at all. NV4500 would work, but OD isnt as much as it could be. the NV5600 has a lower first gear to make up for taller gears if you like.
