The clutch housing is also made of cast iron and features a heavy-duty clutch release bearing and a 9-inch clutch disc.

The M22 transmission is also equipped with syncromesh gear teeth, which provide smooth and precise shifts. The transmission also features a double-overdrive design, which allows the engine to operate at lower RPMs at higher speeds, resulting in improved fuel efficiency and reduced engine wear.

The M22 transmission is available in several versions, including standard, heavy-duty, and competition versions. The standard version is suitable for street use, while the heavy-duty and competition versions are designed for high-performance applications.
