I havent driven it yet and right now I have the carb apart for a good cleanin and new gaskets. The gear shift indicator on the colum is so unfamilier I realy cant tell ya if it's a 4 speed or 7. There seems to be a sticker on the dash about shifting something, but the only thing I can tell from it is, it used to be a sticker at one time. The guy I got it from bought it, drove it to the barn to "restore" it 20 years ago and thats as far as he got. I trailered it home, got it runnin a couple times but it hasnt moved yet. As far as the aux trany goes, all I'm sure about is its a direct/under gear box. Do you know how many different brands of aux tranys they used??????
