Hondas in general can get very long mileages. I have heard of some doing over 100,000 miles and still going. So I don't see the AT being much different.
And if you have DCT-model, don't forget to change gearbox filter also.1) Do oil changes at required intervals, and change the oil filter every time (even if they say you can skip every-other... they are cheap in the grand scheme of things, and why pollute your new oil w/old gunk form the old filter? Not worth the few bucks savings IMHO)
