The famous "rockcrusher" M22 4 speed had the same gear ratios as the M21 but with a heavy duty gearset. Although the gears are not spur gears ( completely straight ) they still produced a fair amount of gear noise thus the "Rockcrusher" name.

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". It is a common misconception that all Muncie transmissions are "Rock Crushers", but it is only the M22 that deserves that name.

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.

M22 Rock Crusher. Just bought a 1968 (originally was 427/435..currently has a CE replacement block from 69)) and I believe it has a M22 vice M21.

Someone correct me if I'm wrong but I think the M22 rock crusher is a close ratio trans with straight cut gears vs. normal helical cut gears?

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 weird,1-2-4-3.
