The '93 FSM says 4 quarts of ATF+ for a service fill and 9.1 quarts for "overhaul fill capacity with converter empty", in other words, a dry never filled trans and converter. As NYBo stated about 5 quarts, depends on how long you let it drain. The longer you let it drain the better because it will drip forever making it difficult to keep the gasket dry when reassembling. I use NAPA filter kit ATP 1-7960 that has the black rubber type gasket and no sealer on my '98 without leak problems. Way back I used to just use sillycone as factory recommended and always had seep/leak problems. I recommend using a in-lb torque wrench on the pan bolts at 105 in.lbs, if I remember correctly, to get even torque on the bolts. Of course, torque the bolts down in at least two steps and in a criss-cross pattern. The reason for this is because that aluminum case is soft and you can easily strip the threads. My trans has had two major repairs and I have had to install inserts in every hole! I think they used an air wrench and weren't careful enough snugging up the pan.
