M-22 "Rock Crusher" Identification The M-22 close-ratio transmission is easily identified internally from the M-20 and M-21 versions by the angle of the gear teeth. The M-22 was only produced in a close-ratio version, so it will not appear on models with high rear-axle ratios (3.55 or lower numerically) unless someone has changed it.
The 2.20:1 ratio is commonly designated as the Muncie M21 transmission. The 2.56:1 ratio is commonly referred to as the M20. Muncie also had a second close-ratio transmission designated M22 and often referred to as the "rock-crusher," which was used behind the highest-performance engines and in Corvettes, the M22 is a highly sought-after performance transmission.
