65 904 leaking pretty bad but don't know where?

I had my pan gasket replaced three times in my 1965 Barracuda Formula S (console shift) and it still leaks tranny fluid. In my case, the first few days parked it does not leak, but then the longer it sits, the more the tranny fluid oozes out from somewhere. Someone said that after a while, the torque convertor fluid drains back to the transmission, and that is when the dripping begins. The dripping location is still unknown. If it is not the pan, it must be a seal somewhere. I did drive the car home (1,500 miles) and did not have a problem on the road with leaks, only when parked/stored. The transmission shifts just fine after I top off the fluid. I hope this info helps in a solution.
