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 dead 2.20 first gear ratio which is the same in the M21 is not that good for off the line acceleration. You would need at least a 4.56 rear end gear to compensate for the dead first gear. That was OK when gas was cheap in 1967 and you did not mind pulling 3000 RPM at 50 MPH while going to work.

Across the top of the page are the words "First Build 4/15/65 – 1st Shipment 4/19/65, recap of M22 (Rock Crusher) Trans." By comparing these M22 transmission assemblies to Chevrolet's 1965 transmission identification codes, I found a perfect match.

The M-21 is the close ratio 4-speed. It was used on high performance models with numerically high rear end ratios. The M-22 was the "rock crusher". It had the same gear ratios as the M-21. The VIN is stamped on the tranny. The location may have varied. I haven't looked at mine in a while, so maybe someone else could be more specific.

TonyMemberfrom Rochester NY. USA. ""You can outfit an M20 or M21 with Rock Crusher type gears, OR actually make a 3 speed O/D out of a 4 speed case. Forth being the overdrive obviously.. Actually the 3rd gear station becomes the OD and the 4th gear station becomes 3rd,so the shift pattern is a little weird,1-2-4-3.

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.

The regular productions codes identify an M-20, M-21, and M-22. Of the regular production codes, one particular Muncie 4-speed type appears. 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.

The M-22 gear teeth are cut at a noticeably lower angle (not quite at a straight angle as some people say). This lower angle of the teeth imparts greater strength to the gears, but it also increases the noise caused by the meshing of the gears. This higher level of noise is where the nickname "Rock crusher" originated.

In addition, many GM high-performance engines came with M-22 "Rock-Crusher" in the 1970-73 years, however an early version of the M-22 was available as early as 1965 in Corvettes. The main internal differences in the 3 types of transmissions are listed in the parts below.
