The M-21 is the close ratio 4-speed. It was used on high performance models with numerically high rear end ratios. The M-22 was the "rock crusher". It had the same gear ratios as the M-21. The VIN is stamped on the tranny. The location may have varied. I haven't looked at mine in a while, so maybe someone else could be more specific.

The "Rock Crusher" M22 internal design is MUCH stronger than the T10. However, if you had the iron cased st10 with a 2.43 gearset; its as strong of an OEM 4 Speed gearbox "system" as you can get, without getting into Hemi 833s (assuming all new, quality parts). Case and point; we build a spec gearbox for SCCA's A-Sedan series.

I started out with Pontiacs in the late '70s, and moved into Mopars because of chronic 4-speed transmission problems. I make no excuses about being a big A833 fan, and in my opinion the 18-spline hemi 4-speed is the strongest of the three. ... Anyway, yes I think the A833 was a real gem. As far as Toploaders go, I grew up in Ford and Chevy ...

The Borg-Warner four-speed transmission played a key role in launching the Motor City's high-performance movement of the sixties. When the Borg-Warner T-10 was introduced in 1957, four-speed transmissions were hardly an innovation. They were nearly as old as the auto industry, and in the 1950s all proper sports cars had to have one.

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.

The Super T-10 (Borg Warner's answer to the Muncie M-22 "Rock Crusher" transmission) as far as I know was never offered as an option in a factory car. The T-10 broke under speedshifting conditions as the brass synchronizer rings wore down causing the gears to chip as they tried to engage.
