How to Identify Muncie 4 Speed Transmissions. Identifying Muncie 4 Speeds III by Paul Cangialosi : The most popular question has to be that everyone thinks they have the famous "rockcrusher" M22 4 speed. This had the same gear ratios as the M21 but with a heavy duty gearset. The reason you may ask?
Serial numbers for Muncie 4-speeds always begin with the letter "P," which stands for Muncie Plant (not "passenger car.") "M" and "N" were used to identify 3-speed Muncies; "O" identifies the Saginaw 3-speed with overdrive. Serial numbers from 1963 to 1966 included only the month and day. For example, P0101 indicates January 1.
It tells how to pick out what is what but the main thing to look for in a M-22 is the gear angle. Take off the side cover and look at the angle of the gears.
