Leaking transmission

[boygenius]

I turned my chassis upside down to install my rear swaybar. I installed the transmission along with the trailing arms. When I inverted the transmission it began to leak gear lube from the top front of the case. It looks like it is leaking from the front gasket between the nose cone and the body of the transmission. Is there a vent there and the leaking is normal or do I have to pull the nose cone off and replace the gasket. Just to let you know the transmission is a brand new built unit.
