Are you sure it is a muncie? If it is a three speed muncie it will be a M62 or M64, the M20, 21 and 22 were all 4 speed. Maybe a few pictures would help someone with a little more knowledge to identify it for you. I am not sure but I think the muncie would also be an aluminum case where as a borg warner or saginaw would be a cast iron case.

Post a picture; but it sounds like you have the old muncie 3spd from the 50's. As Kelly said; the M20,21 and 22 are all aluminum cased 4 speeds.

If all you need is the ratios; theres no guarantee that what the General put in that case 50yrs ago, it exactly whats in there after 50yrs of service and owners. Your easiest answer is to put the trans in 1st gear and turn the OUTput shaft 10 times, and count the number of times the INput turns. then divide that number by 10. There may be enough slop in the transmission that you wouldn't be able to find the difference between 2.4 and 2.7 for example by only turning it once. Hence the "10 times" method; it'll cancel out most of the slop. Do this for all your forward gears and you'll have your ratios.

Definitely post a picture
