Although the gears are not spur gears ( completely straight ) they still produced a fair amount of gear noise thus the "Rockcrusher" name. These 4 speeds sound like a blower drive. For the real gear head the best documented movie that sports a real M22 in a car is the famous movie " Two Lane Black Top". You can really hear this gear box howl in ...

3500 x 3.08 / 4.10 = 2629 RPM. Using an M22Z with a 3.08:1 is like having an OD with a 4.10:1 AND you still have the takeoff feel of an M22 and a 4.10:1 combination. The M22Z and the 3.08:1 combination is not the answer for everyone but, it is another option. Jody Haag 610-413-8015. Jody's Transmissions on Facebook.

Just three types of Muncie 4-speeds are available based on the RPO (regular production option) code used when a car was ordered: the M20 (standard wide-ratio), M21 (close-ratio), and M22 (heavy-duty close-ratio). (The M does not stand for "Muncie.") Typically, when you ordered a GM car you had standard options and accessories installed.

To do so, it needed an even tougher gearbox than the M21, and while the Grand Sport never made it to Le Mans due to GM politics removing its brands from motorsports competition, the Bowtie brand was able to test the Muncie enough to develop a newer version that eventually hit the streets as the M22. The M22 'Rock Crusher' …

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.

The M22 is a serious beast when it comes to transmissions. The only negative was the noise that this transmission would produce. When the engine was driving at low revs the transmission would rattle like it had gravel inside and would whine at high rpms. The M22 was eventually dubbed the "Rock Crusher".

The term "rock crusher" refers to the noise made by the meshing of the stronger helical gears in the M22. Later model 1971-'74 Muncies are also popular with racers, because these transmissions used a 32-spline output that is stronger than the early 27-spline, and the newer units seem to perform better in high-rpm and high-horsepower ...

Input shafts differ in each GM transmission, so you can easily identify an M-22 "Rock Crusher by its input shaft count. Each transmission has different numbers of teeth. An M-22 "Rock Crusher" always has 26 teeth. Count the number of splines in the transmission. M-22 "Rock Crushers" made between 1967 and 1970 have 10 splines ...

from Southern Ok. ""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 d,1-2-4-3.

If your sure its a real M22, its a pretty rare transmission. THey go for about $800-1200 on EBay depending on condition. I know because I was once looking for on until I got a Borg warner instead. If its an M22, the input shaft should have no rings on it and the spline count should be 26. They are nice transmissions.

Why is the Muncie M22 called the rock crusher? October 12, 2022 by Carolina. Spread the love. The reduced gear angle of the M22 created a problem with noise (hence the name "rock-crusher"). Performance seekers decided to live with the noise when the benefits of increased durability from the gear-tooth angle outweighed the …
