Muncies with 26-spline inputs and 32-spline output shafts came as M20, M21, and M22 transmissions. Before 1969, only M22 transmissions had drain plugs. From 1969 to 1974 all-ratio Muncies came with drain plugs. Muncie countergears had the same number of teeth on first-, second-, and third-speed sections.

The M20 and M21 cluster gears are cut at a 45-degree angle. The reduced gear angle of the M22 created a problem with noise (hence the name “rock-crusher”).

Various gear manufactures make replacement gear sets for M22''s that will fit in any case with a 1" countershaft. The replacement gear sets do not have identifying rings on the input shaft to tell the ratio. Again, the only tried and true way to tell if it''s an M22 is to pull the side cover and look at the gear angle. Vince
