How can you tell if you have a rock crusher M22?
Look for the “GM” sign imprinted on the transmission box to identify the manufacturer of the transmission. Check whether there are any rings around the shaft splines. An M-22 “Rock Crusher” has no rings, so if you see rings in your transmission, it means it is not an M-22 “Rock Crusher.”

It is the heavy-duty version of the 2.20:1 ratio M21 four-speed.
Why is it called a rock crusher transmission?
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 gravelly clatter.
How long does it take to set a rock crusher?
Quickly insert the 3-foot iron rod into the cement. Move it until it stands at the center of the pipe. You may have to prop it in place by fixing a C-clamp to it and laying the clamp on the top of the pipe. Let the cement dry — even quick dry cement may take 4 to 6 hours to set.
