In the beginning, the M-22 was the Heavy Duty Muncie, and it was available ONLY in the close ratio version (2.20:1 first gear ratio). The primary difference between the regular close ratio Muncie (M-21) and the HD Muncie was the angle at which the gear teeth were cut.

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. M-20, m-21 will have 45 degrees gears and the m-22 is 22.5 degrees. They used this to reduce friction and in turn gave it a nice greary noise thus the rock crusher. Chris

The M22 was eventually dubbed the "Rock Crusher". It is a common misconception that all Muncie transmissions are "Rock Crushers", but it is only the M22 that deserves that name. The M20 and M21 were both release in 1963, but it wasn't until 1965 that the M22 hit the market. The M22 was created for the Corvette Grand Sport racing program.

The FACTORY M-22s were ONLY a close ratio version (2.20:1 first gear). The aftermarket M-22s are available as either a close ratio or wide ratio (referred to as an M-22W with a 2.56:1 first gear). If your car has a 3.55 or higher rear gear, you would be happier with the M-22W. Again, contact Wally.

""You can outfit an M20 or M21 with Rock Crusher type gears, OR actually make a 3 speed O/D out of a 4 speed case. Forth being the overdrive obviously.. Kinda nice if you want the Muncie look and an overdrive"" Actually the 3rd gear station becomes the OD and the 4th gear station becomes 3rd,so the shift pattern is a little d,1-2-4-3.
