Help coolant leak

I have a 1969 xj6 manual with overdrive.I have a small coolant leak when the car sits coming from the small hole on the bottom of the transmission.pressure tested system with no leak and doesn't leak when car is running just a small spot 1" circle after car is stopped.I don't think there's a freeze out plug behind the trans bell housing but I could be wrong.HELP any thoughts?
