Didn't work with a cork gasket. I think the pan in the passenger rear corner is warped. I tried it again, draining and saving the freshly installed fluids. I added a rubber gasket plus some special Permatex RTV for transmissions. (NEVER use normal RTV on a transmission gasket because it will be dissolved by additives in the transmission oil.)
Still didn't work. I'll pull it again and hammer on the pan to try to true it up. We'll see.
For what it's worth, I'm not frustrated much by this. With the drain plug in place, it's much easier to repeatedly drop the pan as I try to get the leak fixed. I'm gettin' real good at it.
