I have developed a small seap type leak on the lower front of the AW71. I cannot ascertain whether it is engine or ATF oil, it's to dirty by the time I find it. The fluid appears to come out of the louvers on the bottom of the tranny under the tourqe converter, however, I do not experience any mechanical or fluid level problems. Ideas...could the rear main seal leak out here, or does the tourqe converter have a seal that could leak? Appreciate comments.
