And in addition the TU should have a breather on the drivers side of the case. Much easier for fluid to exit there than up the fill pipe. It was easy enough for fluid to exit the breather that in 56 Packard issued instructions on relocating it to the top of transmission rear extension if evidence was found fluid was leaking from the breather.

If fluid goes all the way up the fill pipe, I'd wonder if the breather was plugged as well as if there are any cooler issues. Perhaps fluid leaked and breather was removed instead of relocated. Since the fill pipe opening is in the pan and well below the normal level of fluid, without a breather to relieve pressure the fluid would surely be forced out.
