R154 leak seal problem? help

[JP85MX73]

Im doing a 1j swap into my x7 and when i was test fitting the engine as the tranny pointed down on an angle all the fluid leaked out of the driveshaft hole.. does this mean i have a bad seal?? or is this normal?

100% normal.

The driveshaft yoke acts as a plug....the rear tailhousing seal seals around the driveshaft similar to an engines rear/front main seals....or cam seals.

As sc said (100% normal!)
