Well if you had a bucket of fresh fluid and stuck the retun/inlet line into it then I'd probably say it would be ok.

If you do this while the car is cold then it would be better as than hot. You don't want to loose all you ATF when the transmission is already hot.

Hell, it probably won't matter either way. If it is idling in park while you do it as there is no pressure on any clutch packs or bands at that point. I'd just be a little leary if it was already up to operating temp. I say this last bit about it not mattering because how many times have people with trans leaks leaked run low on oil and realize it later then fill up and everything is still fine. And that is with pressure on everything.
