Hello all,

Just bought a 1997 Passat glx Vr6. I have a **** colored fluid leaking from underneath, but I don't know what it is! It is not antifreeze. It appears to be coming from a cylinder shaped piece at the front side of the transmission. I don't know what this piece is, or what the fluid is. The piece looks like a cylinder, with a cap on the end of it. The cap has a hexagonal "nut" on the bottom of it. Any ideas?????
