"Another change for the M22 was the new low helical-angle cut gear set which increased the inner strength of the transmission dramatically. This gearset was quite noisy and from all indications was called the "Rockcrusher" transmission from the beginning by all Chevrolet and Muncie engineering staff."
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.
