The only thing I have noticed with automatic transmissions is as follows:
Shifting in to N with my Camry results in more coasting ability, but it also uses, like was said earlier, a little gas to maintain it's idle.
Leaving the tranny in D when I coast results in a little more loss of speed because, I figure, it's using the wheels to keep the engine idling and adjusting the amount of spin getting to the engine by using the transfer case to modulate how much goes from the gears to the engine. I figure this because when I let off abruptly going down a hill, the RPMs will drop down to idle and then after a second they will jump to 1100RPM (from 800RPM). I have not gotten a scangauge yet however to confirm this idea).
