Leaking Tranny Fluid

I have a 727 in a truck that doesn't get run much and i power washed everything as best as I could without pulling the trans, and I was under the truck, the last couple of days. It has a leak, that seems to be seeping thru the threads for the front band adjustment threads.
I'm sure it has drained back into the case, with as long as it has sat undriven.
My truck has been sitting since last fall, I jacked up the rear a couple of weeks ago and it has been sitting on stands since, fronts sitting on the tires/not jacked up.
Seems like I've started noticing the wet spot underneath just since I have had the back end up on stands.
