I have not had that issue, though I have had a little fluid leak out of one of the drain plugs and the filter housing. Both were resolved by tightening or re-seating. I had a real hard time with one of them because the fluid was blown around by the fan, so tracing became impossible. I ended up cleaning the entire transmission, then examining it every 15 minutes of use until I was finally able to locate the leak (transmission filter housing).
