The torque converter is able to absorb most of the N-D shock at motion.
Dr. Jerryrigger mentioned rev-matching, which avoids most of the shock to begin with.
What it doesn't I wouldn't worry about since the transmission is designed to take repeated WOT high rpm shifts where the engine is turning 6000 or so RPM and the next gear is down at 4000 and that much of a change at idle or right off it is nothing in comparison.
Totally agreed. The amount of work that it needs to do to make everything match is a lot less than it has to do during a high-power shift.
Glad someone knows what I'm talking about.
My favorite is the beat up Cavaliers with different color fenders, $2000 rims and ether an expensive muffler that doesn't muffle, or a rusted out exhaust (I can't tell the difference)
And who can forget the minivan with the spinners. And of course blasting that song. It's funny I can't get NPR in town so I often end up listening to "fun 107" and you can't listen to that crap unless it's blasting... I've been assimilated.. but i still drive like and old lady
