An M22 retains less heat due to the straight-cut gear design and the lack of thrust that helical-cut gears create. An M-22 holds up well. The downside is that it tends to make noise. It will rattle at low rpms and whine at higher rpms. The M22 is called the Rock Crusher. “Dump the Rock Crusher,” hot rodders say.

The M22 transmission has a 20 degree helix angle on the gear set as opposed to a 45 degree angle found on the M20 and M21 and were made with a higher nickel alloy. The straighter angle was designed to produce less end loading of the gear train and less heat but created more noise, thus the nickname Rock Crusher was born.

May 25, 2020 At one time, an M22 had a rather high value. But now, I have some reservations about the value of an M22 for several reasons. First of all, the M22 is ONLY a close ratio transmission, with a 2.20:1 first gear, thus, it is not idealy compatable with a high geared rearend ratio such as a 3.07, 3.31 and marginally with a 3.55-----and certainly not with a 2.73!

The progression of the 10-spline input identification groove system. From left to right, early M20, M21, later M20, and M22. You really cannot get the early M20 and M22 mixed up because the early M20 came with a 7/8-inch countershaft, while the M22 did not. In fact all of the upper-speed gears have the same tooth count regardless of ratios.

The term rock crusher refers to the noise made by the meshing of the strong-er helical gears in the M22. Later model 1971-'74 Muncies are also popular with racers, because these transmissions used a 32-spline output that is stronger than the early 27-spline, and the newer units seem to perform better in high-rpm and high-horsepower applications.

Muncie also had a second close-ratio transmission coded M22 and known as the rock crusher, which was used behind performance big-block engines and in some Corvettes. These M22 units are highly sought-after for performance applications. The term rock crusher refers to the noise made by the meshing of the stronger helical gears in the M22.
