Bulletproof may have been a poor choice of words. The dodge autos of there 94-2007 (pre 6.7 6spd autos) years are nothing more than glorified 727 tourqeflites with overdrives. The HP doesnt hurt the auto, its the torque, and a poor torque converter design. They have a tendency to come apart. As far as manuals go, they are the best bet in a dodge. The NV5600 is a iron case with larger internal shafts and gears than the G56. I ve seen both apart and can honestly verify this.
Catmando, watch any 3rd to 4th hard shift. Just rebuilt a g56that broke 4th gear. Guy was towing a tractor on a gooseneck.

Nobody on the Cummins diesel forums has anything good to say about those TC/s.I hear ya on the 3rd to 4th shift. When I'm not towing(which is all the time these days
) I start off in 3rd. Then I give the trans some extra time to get into 4th, especially if it's the first shift of the day. The fluid needs to warm up. I do a lot of downshifting in town too so the trans warms up fast.

618/1442 is serious power for a daily driver. When my wife retires we'll buy a big toyhauler and go full time RVing. I'll do some mods to the truck then to gain more torque and keep the EGTs down but I don't care about hp. I'm going to keep this one it's the 5.9.

Catmando, the G56 replced the NV5600 at the 2005.5 year mark. It is in no doubt a good transmission, lighter weight, closer gear pattern, but the NV 5600 does have heavier built internals. Also, it has a cast iron case as the Gertrag G-56 has an aluminum. Throw a dual disc clucth, a air dog 150 pump, smarty and MP8 on your 06 and go rip up some A$$PHALT

I think Dodge went with the G56 and the common rail motor, not the NV5600. I could be wrong though. I know mine is the G56. The Getrag is a really good unit, and Dodge uses it even in the 4500-5500 trucks.

618 is fun, but there are plenty others out there making more.. lots more than me.
