 ====Identifying Muncie M20 series transmissions====
 The external differences between the three Muncie 4 speed transmissions can be deceiving. If the cover is removed, the pitch of the gears can be seen. In order to tell the difference between an M21 and M22 definitively, look at the helix angle on the gearset. M20 and M21 have a steeper pitch, where the M22 will have a less aggressive pitch. M22s are NOT straight-cut or 'spur gears'.

 Put the transmission in 1st gear. Turn the input 10 times while counting how many times the output turns. If it turns 2.5 times, its an M20 (2.52 1st gear). If it turns 2.2 times, its an M21 or M22 (2.20 1st).
-If you determine it's a close ratio M21 or M22, remove the sidecover and look at the angle of the gear teeth (refer to photo above) to see if it's a M22 or not.
