Hy guys, I have an auxiliary transmission in my newly aquired 1946 Chev 2 ton cabover. There is no ID. plate on it, it has two shift rods on it that are passing through the main housing not in the cover. I'm assuming it is a three speed, but I'm not sure, I've looked in my old books, but most show a trans. with the shift rods in the cover. Anyone have any idea what this trans might be??? Thanks
