I just bought an Attex and don't know the first thing about 6x6 AATVs so am sure happy to see all the great info here. Mine has a Kohler engine swapped into it and so far I haven't found anything that looks like the drive setup mine has (doesn't have a transmission like the manuals posted show - more of a straight shaft). I don't know if it's a modification, early model or what and am not quite sure how to figure it out other than dig thru 6x6 World and hope I find something. I can't wait to get it going!
