ok so i just replaced the trani in my 94 f2 got it all reassembled everything is great. i rode it over 100 miles now and i noticed the overflow hose for the coolant reservoir was dripping brown fluid. i poped the cap off and the reservoir was full. i can tell there is oil in the coolant. i drain the oil and it has NO coolant in it. still looks new. how is this possible? i cant think of how oil would get in the coolant but coolant not get in the oil? could really use some help here!!
