Found a web site listing eaton fuller trans. gear ratios and how to id
useful info on eaton fuller trans gear ratios found at this site. 9 10 13 18 speeds. Posting one address. To view other speeds just change the number in the address ie. 9 to 10. 13 or 18. Interesting I did not see a 13 speed single overdrive listed. Maybe you get that if one converts a 9 speed to 13? Many 9 and 10 speeds with single over. Also learned that single overdrive models can have different over ratio.
If you go to home page you can find links to other brand transmissions and axles.
Is this a worthwhile discussion?
