I have a strange location for a trans leak. It's on the side of the bell housing. I did a full fluid and filter change and the radiator bypass about a month ago. But today is the first sign of a leak. I am out of town so my wife noticed it and took this picture. I suspect the lines are leaking but what is the black thing bolted to the side of the bell housing? You can see the drip at the bottom of the black piece.
