I'm noticing a very slow leak of some sort of fluid from under the front end of my 99. Only problem is that I can only see it keeping the frame crossbar moist, not the actual source. As best i can tell it's located on the right side, directly beneath the oil filter and the starter. When I put a drop on my finger it appeared very dark-almost black, and when it was on a cloth it looked as if it had kind of a yellow-ish gold tint to it, yet still very dark. My steering, washer, and coolant reservoirs are all full and my oil is both full and clean, not black. My only thought is that it may be tranny fluid, but that's usually pink, right? Any ideas on A) what this might be and B) how I can find the source of the leak to get it fixed?
