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.

In 1966, this changed to RPO M-20, RPO M-21, RPO M-22, and the customer more or less selected the 4sp option (within limits, for example, you couldn't get the M-21 with a 3.07 rear). The M-22 (HD, Rockcrusher, whatever you choose to call it) WAS NOT available as an option until 1966.
ORIGINALLY, in the beginning of the Muncie evolution, there was the M20(wide ratio) and the M21(close ratio).
