When I dropped the two pans I got maybe 1/3 of a quart of fluid out of it, so basically dry. I'll be honest, I was worried that I was going to need a replacement.

A couple gallons of Dextron III, a quart of Lucas Oil's Magic Wonder Concoction and new gaskets and a filter and the transmission is now working great. So grinding, no slipping, and (so far anyway) no leaking.
