This is how the Muncie countergear's design evolved. The center gear is from a BorgWarner T85 3-speed. The lower gear is the latest version of the early T10 and the upper is the Muncie M22. Note how the Muncie gear is physically longer than the T10. The reason for these design changes was simply to meet the demand for increased torque …

By the time the Muncie was in its final phase of production (1971-1974) it also gained a 32 spline output shaft in place of the original 27 spline unit.

Let's say you have an 4.10:1 differential and you would like a 5 speed but the $4,500-$5,000.00 price tag is too much for a 5 speed complete kit.

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 …

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". It is a common misconception that all Muncie transmissions are "Rock Crushers", but it is only the M22 that deserves that name.

1963-1966 production codes will start with the letter P and have four numbers, for example: P0421. 1. P represents the manufacturing plant, Muncie.
