taz3. The M22 is not physically stronger then the M20 or M21, the difference is the way the gears are cut. The M22 was originally designed for road racing, where temperatures were increased with the steeper cut gears of the M21, so the M22 was design with a straighter cut gear to reduce heat.

R. Rick_L · #2 · Jul 6, 2011. I would not recommend a Muncie M22 or M21 for any street driven or drag race car. It's simply not the right gear ratios for anything but road racing. The 2.20 low gear is just not low enough. If you want a 4 speed, get a Muncie M20 with a 2.52 low gear ratio.

Spread the love. The M20 and M21 transmissions produced from 1963-'74 are easy to identify in both wide- and close-ratio units. The M22 to come later in 1967-'74 is also a close-ratio unit, but much stronger than the M21, with a higher torque capacity. Table of Contents show.

The first time I heard the term "rock crusher" was in reference to the transmission in the 1967 L88 Corvette. Due to the low gear angle there is a fair amount of gear noise, really like a medium / heavy duty truck transmission. True enough the M22 did trickle out the door in 1965-67 and was buried in the option lists.

I have a 68 Camaro with the original L48 (engine pad # matching Protect o Plate number), mated with a transmission that I was told is a Muncie M22. The transmission also has the right VIN stamped on it and the # matching the Protect O Plate so I know is the original that came with the car. The transmission whines line an M22 and is close ratio.

The engine was a 425ftlb Gen2 Coyote sealed crate engine making a low 10sec pass @ 3100lbs. Note that how fast the clutch pulls the engine down has a huge effect on the height of the torque spike.

TonyMemberfrom Rochester NY. USA. ""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 d,1-2-4-3.

THUS, the split between gears of the early and late versions was different. The "new" M-22W has the early style 2.56 1st gear, therefore, it does NOT have the same gear split of the later, more common M-20s. This makes the new M-22W slightly more compatable with rear gear ratios in the 2.73-3.55 range.

At one time, an M22 had a rather high value. But now, I have some reservations about the value of an M22 for several reasons. First of all, the M22 is ONLY a close ratio transmission, with a 2.20:1 first gear, thus, it is not idealy compatable with a high geared rearend ratio such as a 3.07, 3.31 and marginally with a 3.55-----and certainly not …
