Congrats on the truck. I just went from a '06 5.9 to the '15 6.7 HO with the Aisin. I can't wait to pull with it! I have about 100 miles on it so I need to start breaking it in. At about 2000 miles on it I'm going to fill my toy hauler to the max and tow it from Sac to the 80 summit and back a couple of times to break it in. It will burn some fuel but I think it will be good for the truck and help with MPG in the long run.
Once you have 500 miles on the truck, you should be able to tow with it...The other recommendation is about towing the first 500 miles, manual states to not drive over a certain mph and to vary speeds..
