My Jeep truck sits a lot now, and the rear seal begins to leak after I park it for about a week. It is fine as long as I am using it pretty regularly, but once it is parked it starts, and gets worse and worse until I add some fluid and drive it again, then it stops for a while.

I'm waiting until I freshen up the engine and put in another AOD I have waiting to go in there, so I just let it leak and add more for now.

See where yours is leaking by putting those oil absorbent pads you can buy at any marine store, for about a buck each. Put a few under there and see where it is hitting the pads.
