That sounds like mine. Some chattering and growling at low rpm is normal for mine and I know it is in great shape. I check the magnet for wear metal at every change and over fill with 6 qts. Craig

The gear rattle is normal at low RPM's. I think it is caused by the engine actually speeding up and slowing down between each power stroke.
I replaced the harmonic balancer with the fluid damper for the 6.7L. Cost of parts was just under $300. It did reduce the rattle but did not eliminate it.

if you have a dual mass flywheel, that would be the problem

The dual mass was not re-used in our trucks until 2006....worst idea known to man!!!! The 04.5 still had the single mass flywheel.

Agreed, the shuddering/vibration is normal when lugging with a NV5600 behind a Cummins.
Wait until you install a HD aftermarket clutch.  Don't lug it. Keep the RPM's above 1800 for the stock clutch. Above 2000RPM with an aftermarket clutch. You can imagine what the Cummins low RPM lugging vibration does to an auto trans.
