need some Hemi help

I have a 2003 Ram 2500 with a 5.7 lt Hemi. It has developed a coolant leak that seems to be coming out between the block and the bell housing. I assume there are core plugs back there but have never had one of these out of the vehicle.
Is my assumption correct? or is there someplace else where that coolant could be coming from?
I have checked the back of the intake manifold and the heater hoses, they are dry.
I'd sure like some input before I pull the transmission/transfer case.
