I too am curious what would cause this leak. Mine was leaking and when we had the motor out you could see dampness under a couple of the pump bolts. I replaced the rubber coated washers and still had a leak. Pulled it back apart. Converter is completely dry on outside. Looked like the seal around the pump was the problem. replaced the gasket, o ring, seal, pump washers and put back together and guess what??? Yep, still leaking. I have a blanket on the trans and was wondering if it may be blocking the vent and causing a problem???
