75% chance its coming from one of the two haeter hoses. They fail often, especially at the firewall nipples. The coolant leaks down to the tranny to make it look its coming from there.

20% chance its coming from the TB or rear-plate coolant nipple.

5% chance its a rear plate leaking from the rear seals.

Is there anything wet under the pump?

Did you follow Kenteth's advice and check the heater hoses at the back of the engine?

Umm, black rubber hose, about 1" in diameter...The specific areas you want to look at are 1)6" directly underneath the oil filter, coming out of the block 2) underneath your upper intake manifold, at the very back of the engine (get a mirror for that one), and 3) the bottom of the water pump "shaft" (mirror helps here too)
