M22 Identification

This bumbed me out since I had previously read that this was an indication that it was a Saginaw not a Muncie. It does have a 7 bolt side cover. Doe this mean it's still an M22 but just manufactured at the Saginaw assembly plant or it's not an M22 "Rock Crusher Transmission". I am just learning !

When was the M22 first called "rock crusher"?

I became aware of the nickname, likely a motorhead created comparison of the rugged transmission to rock quarry equipment, when, in late '68, a buddy traded a whipped '66 SS396 for a disaster of a 1962 Corvette with a 1965 396/425 engine and an M22 transmission, 4;56 ratio '62 style rear end, unbelievably cobbled shifter, cooling system and ...

M22 Rock Crusher

M22 Rock Crusher. Jump to Latest ... If the trans needs repair, there are no new gears available for these units, for that matter any Muncie.

Muncie M22 Rock Crusher 4 speed

I do not claim to be a transmission expert and could be wrong but the "real" rock crushers had straight cut gears....not 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.

Gear ratio difference between M20, M21, M22

IMHO save the close ratio gearsets of the M22 for use ahead of 3.73:1 and larger ratio rear ends, and FWIW I wouldn't go smaller than a 3.36:1 rear gear even with a wide ratio Muncie box. Forget the Muncie OD, unless it's going in your pickup truck. BTW, you can now buy high-quality M22 "rock crusher" style wide ratio gearsets!
