I do not claim to be a transmission expert and could be wrong but the "real" rock crushers had straight cut helical cut gears I believe they were first released by GM in 1969 or 1970 I had one in my 1970 Chevelle SS 454 450HP LS6 car I bought it new The Rock Crusher was very noisy due to the straight cut gears
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
They used this to reduce friction and in turn gave it a nice greary noise thus the rock crusher Chris m22 The only way to be 100% sure is to pull the side cover and check the gear angle like the others have stated Depending on the year of the transmission there are some things to look for but as vince stated if the parts were swapped
