Hi Ray,
Long shot, but do you have a Ragussa alum pan? I have had issues with those weaping oil which went everywhere making it hard to really pin point the source. My suggestion would be to clean everywhere under the coach with brake cleaner and rags to get everything around the transmission dry and clean. Then add dye to the trans oil and drive it around until you see the oil under there again. Use the black light specified by the dye maker to see if you can tell the source. I went through something not as severe but just as frustrating until I replaced the Ragussa alum pan with a new one JimK now carries. Issue solved for me at least. That said, I never found the trans four quarts low so if the dip stick is calibrated your oil is likely going somewhere other than out through a leak.
