Help with Torqueflite 904

I just pulled up a parts catalogue from an Australian Automatic Transmissions supplier, and they are listing the following

Valient / Chrysler 6 & 8 cyl - T/Flite 6 (904) & 8 (727).
Sigma Scorpion (Sapparo) T/Flite 6 904 Baby.

They list a completely different filter service kit and they are running a different pan gasket to each other which confirms there variations to each other.

I am trying now to get some in depth part number comparisons between the two model 904 boxes to exactly see which parts are different and which are the same. I will let everyone know.

I also received and email from a couple of USA auto transmission firms who have confirmed that the 904 does have a "Baby" model and that there is a large degree of interchangeability between the two.
