If the vent hole on the rear of the gear shift tower of the transmission is plugged it will cause such a leak like you have . look for a hole about three sixteenths in diameter about half way up the rear of the tower . This hole vents the backend and transmission . Pressure can built after a while and the gear oil will find the easiest exit .
