In late '69, ALL Muncie 4-speeds got both a fill and drain plug. This means that the dual drain plug cases were used in '70-up production although there might have been a few that made it into super-late '69 production, who knows. Before then only the M-22 "Rock Crusher" had them both.

M-21 close ratio, and the extra heavy duty close ratio" M-22, also known as the "Rock Crusher". The M-22 was generally installed behind severely powerful (high torque) big-block engines.

The ST-10 is strong and smooth shifting. It is a much better tranny than a stock muncie (in my opinoin). 68 Camaro, 555 big block, Doug Nash 5-speed, 3.54 gear. there are some very nice parts available now for the Muncie trans. You can get a heavy duty Super Case, and new gears with more ratio selections.

3500 x 3.08 / 4.10 = 2629 RPM. Using an M22Z with a 3.08:1 is like having an OD with a 4.10:1 AND you still have the takeoff feel of an M22 and a 4.10:1 combination. The M22Z and the 3.08:1 combination is not the answer for everyone but, it is another option. Jody Haag 610-413-8015. Jody's Transmissions on Facebook.

In the beginning, the M-22 was the Heavy Duty Muncie, and it was available ONLY in the close ratio version (2.20:1 first gear ratio). The primary difference between the regular close ratio Muncie (M-21) and the HD Muncie was the angle at which the gear teeth were cut. ...

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.

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.
