I do that with domestic vehicles that don't have a tranny drain bolt. Though I find I'm not able to get the tubing to go deep enough to get as much out as you could with a drain bolt. Sure is a heck of a lot better than doing nothing though, and helps replenish the lift of the ATF.

With motor oil I don't bother to do this though for 2 reasons: you need to get under there to replace the oil filter anyway. And if any sediment has collected in the bottom of the oil pan, it is more likely to leave through the drain bolt vs getting suctioned out.
