There also was a second, heavy-duty close-ratio version: the "Rock Crusher" (M22) that was offered on some of the high-performance big-block models, starting with the 1965 Corvette.

Several things are needed to identify a Muncie four-speed transmission correctly. One of the best ways to identify a Muncie is the casting numbers on the external components of the transmission ...

A properly set up M-22 Rock Crusher transmits up to 700 hp, so this stout transmission is a wise choice for high-performance applications as well as authenticity. But that is not a definitive method for positively identifying the transmission.

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.

Since the original M-22 was ONLY available in the close ratio version, there is NOW an M-22W. This M-22W version is simply a wide ratio version (thus the W) of the M-22. Since the M-22 was only a close ratio tranny, it was usually only available, and more compatable, with the lower ratio rearend gears such as 3.70, 4.10, etc.

The gears in this model are extra wide to ensure long gear life and optimum performance. This transmission can be used with a Long H-pattern or Vertical Gate shifter. Many of the Super Stock and NSCA competitors have switched to the G-101 for improved reliability. The G-Force G-101 4-Speed. Transmission is shown above.

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. True enough the M22 did trickle out the door in 1965-67 and was buried in the option lists.
