It would be crazy to hear that you replaced an entire engine and managed to put the coolant into the wrong place lol. If you put coolant directly into the radiator, I cant imagine it would make its way out of the mating surface between the engine and trans. Just no way that can happen. My 05 Accord occasionally leaks some coolant, from the upper hose that goes under the air intake hose. Thats, to the best of my knowledge, the only way to get coolant to make its way to the area you just described. Get back with some pics or a link to a youtube vid.
