Guys I did a lot of research as to what in the world our mystery factory fill ATF could be, and I think I finally found it. After a lot of searching, and phone calls to shell USA I have deduced the following:
According to the australian petrolium institute:
http://www.lubeandtune.com.au/html/lubekey.asp their ASP15 classification includes the following fluids:
-Ford Specification No. M2C 919D
-
Mercon SP Fluid Part No. XT-6QSP
-
Shell ATF M-1375.4
-
ZF 6-speed Automatic Transmission Fluid, (Shell M-1375.4)
Mercon SP Fluid is a newer transmission fluid made by shell for Ford dealers. Its easy to find online, and it retails for around $4:00+/quart. Things get really interesting when you look at the specs of lifeguard 6 found in the MSDS:

VERY similar specs, and the same color fluid.
