This is the current Muncie M22. Your can see that the layout of the geartrain is identical to the ST10's. All gears and synchronizers are in the same position. Notice how the angle of the M22 gears is much straighter than on the ST10. The noise level increased because of this angle, giving the M22 the nickname "RockCrusher."

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 most popular question has to be that everyone thinks they have the famous "rockcrusher" M22 4 speed. This had the same gear ratios as the M21 but with a heavy duty gearset. The reason you may ask? Well it wasn't designed so that you could go drag racing on Saturday night or impress in front of Burger King by doing massive hole shots.

1969-1974 codes include a suffix letter at the end to aid in identification of transmission ratios. A = 2.52 1st gear wide ratio M20, B=2.20 1st gear close ratio M21, C = 2.20 first gear Rock Crusher M22. One example code would be ( P0E21 A ) which reads: Muncie four speed aluminum for passenger car, 1970, May, 21st, ratio M20.

In 1965, GM introduced an even more robust version of the Muncie transmission, known as the M22 or "Rock Crusher." This transmission, with its distinctive whine, became synonymous with high-performance cars of the era. The M22 featured straighter cut gears, providing a more aggressive gear mesh for increased strength and durability.

I had a 71 GTO with a M22 "rock crusher". This was an absolutely stout transmission. Had a distinctive "whine" due to the slanted gears. Click to expand... M22 had straight cut gears, all other Muncies had helical cut gears. The straight cut gears gave the M22 it's different sound. Other Muncies were quite compared to the M22.

The M22 'Rock Crusher' featured a one-inch countershaft pin bore and shot-peened gears with aggressive helix angles that reduced heat and stress but also increased noise, leading to the nickname as the transmissions rattled their way down the road.

Although some claim that the M23 is a 'rock crusher', it is indicated that this box was assembled in both wide and close ratio components and also with straight cut gears common to the rock crusher (M22) transmission. Looks like you have a second design-feb. 28th, 1968, M20 or M21. Definitely not a rock crusher(no straight cut gears).

There is also no such thing (officially) as an M22 "rock crusher"... the "rock crusher" name comes from the noise generated by the reduced helix angle on the gears... Not entirely sure, but I think the new "M22 Wide" still uses the same helix angle, and therefore, probably just as noisy...

The first time I heard the term "rock crusher" was in reference to the transmission in the 1967 L88 Corvette. Due to the low gear angle there is a fair amount of gear noise, really like a medium / heavy duty truck transmission.
