If its on the very bottom leading edge of what would be the "bell housing" near the bolts that hold the tranny to the engine block-
Then you may have the typical thermostat housing leak.
Mine was this way, I thought it was a possible tranny leak but I wedged a rag between the upper tranny "bell housing" and lower/bottom section of the thermostat housing. It ended up being "moist"..... so at least mine was the thermostat housing.
See if this helps....
If not throw the SVTF on ramps, use either engine degreaser or Simple Green and wire-brush/steel wool, clean the suspect area up, and drive around for a week. Throw it back up on ramps & inspect....
