This qty. may very well be negligible, but if it's added to amount of oil still in your filter, plus amount remaining inside your crankcase after a warm draining, it might add up to a quart. Here's a thought about filter retention - I'd be curious to compare the weight of an unused filter with that of a used one. I suspect that there's quite a bit of fluid retained in there. I strongly suspect that a transmission is a sealed system w/ no outlet for vaporized oil, so I've no clue where that oil is going. Just my $.02.
