I went through two pans and four gaskets, never fixed the leak. Ultimately had the trans rebuilt and it's not leaking now. I suspect it was actually the front pump or seal.

Buy a quality gasket ideally with crush stops (so you can't overtighten them).. You should probably get the manual and use a torque wrench. See if there's a torque sequence listed, but I haven't seen them for pans, so alternate to next-furthest-away and do it in two or more torque steps. If you do that and it still leaks, then its got to be the pump or pump seak or shift shaft seal or something else running down.

And even if the old boys hassle you, use Right Stuff RTV. It's not the 60s when everyone just assumed it was normal that cars should leak.
