727 Transmission leaking

try some uv dye for atf in your transmission and find some dopers black light. lol you can pick up the dye and light from NAPA. then look for the leak in the dark, believe me you can see it you can see it just like the detectives use luminal for blood spatter. One other area to check is seal at the very top of the manual shaft a lot of us forget about this seal, it sould not leak that much unless your convertor drain back a lot.
