I have a leak that looks to be right behind the transmission. A small box with a gasket. Looks like black fluid. Seems odorless. I know tranny fluid is red, and smells sweet. Also tranny itself was covered, but wiped off all the black fluid, and its not covered yet. Tranny may have been covered from all oil valve covers being replaced anout 10-20k ago, but definately a leak near the tranny.
