If you’re having trouble, let’s assume that you currently have an old Muncie ‘Rock-Crusher’ with a 1:1 fourth gear ratio, some 4.11’s out back, and a pair of 26” tall tires putting the power to the ground. Plug those numbers into the equation above, and at just 65 mph you’re churning out nearly 3,500 RPM!

The M22 is a serious beast when it comes to transmissions. The only negative was the noise that this transmission would produce. When the engine was driving at low revs the transmission would rattle like it had gravel inside and would whine at high rpms. The M22 was eventually dubbed the “Rock Crusher”.

The rebuild parts for my rock crusher cost more than what I paid for the Saginaw. I like the Saginaw for everyday driving because it is quieter and as someone said earlier I skip second quite often on the M-22. Unless you are planning on flogging your transmission a lot, I would go with the Saginaw for an everyday driver just because of the cost.

How to Rebuild a Muncie Four-Speed Transmission
M-22 “Rock Crusher” Identification The M-22 close-ratio transmission is easily identified internally from the M-20 and M-21 versions by the angle of the gear teeth. The M-22 was only produced in a close-ratio version, so it will not appear on models with high rear-axle ratios (3.55 or lower numerically) unless someone has changed it.

The M20 and M21 used a gearset with a more angled tooth design on each gear (left). The M22 Rock Crusher used a gearset that features less of an angled-tooth gearing (right).

The M22 transmission has a 20 degree helix angle on the gear set as opposed to a 45 degree angle found on the M20 and M21 and were made with a higher nickel alloy. The straighter angle was designed to produce less end loading of the gear train and less heat but created more noise, thus the nickname "Rock Crusher" was born.

''64-''65 transmissions had a few differences from ''66 and up (smaller countershaft) All Muncies I''ve seen from ''71 on up had 26 spline input, TH400 size output, and drain plug like the M22s.....leading to the unknowing paying big $$$$$ for an alleged "rock crusher" that really wasn''t.

The 1971 transmissions were the same as from previous year, except that the M-21 close-ratio 4-speed transmission was replaced with a stronger version of the Muncie close-ratio gearbox the famous M-22 “Rock Crusher” 4-speed. It was the strongest 4-speed manual ever installed in a GTO. This lineup remained unchanged in 1972.
