Is it possible for the AX15 to leak where the transfer case meets the trans? I got fluid running down the exhaust and dripping from the cross member under the exhaust pipe.
Add this to the engine and front diff leak.

 

Yes...

 

Is there some sort of pinion type seal that is bad then or some gasket?

 

I just parked the jeep and looked underneath. The tranny crossmember is wet on the passenger side, the mount bracket and underside of the intermediate plate is soaked and the fluid has run down the exhaust pipe towards the engine. The tranny mount itself is still dry and where the tc and tranny bolt together is also dry.
I got probably motor oil going down the bellhousing from the passenger side of the engine and the starter is oil coated. Does that sound more like an oil adapter or pan leak?
