Transmition Gearing ?

[InTimadator]

I did a search on this site and couldn't find what I was looking for. I remember reading there is 4 different types of Argo transmissions and there all geared different. I have a GA series Transmission serial # 13849 can someone tell me what gearing I have vs. the other transmitions. Thanks Tim

I don't recognize the "A", the ones I've seen were something else. There is a G, M, and H. G is lowest, H is highest geared.
