The 1965 M22 maintained the 10-spline input and 27-spline output as all other Muncie transmissions from that model year.The 1965 M22 also had the drain plug boss drilled and tapped for a magnetic drain plug.

Any Muncie four speed will bolt up in place of a Saginaw four speed. The bolt pattern, bearing retainer diameter, and overall length are exactly the same. You can reuse the original driveshaft. The only issue is that M22s use the larger yoke from a TH400. Lesser Muncies use the smaller yoke as seen on the TH350 and Saginaw transmissions.

from Southern Ok. ""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.

Muncie also had a second close-ratio transmission coded M22 and known as the "rock crusher," which was used behind performance big-block engines and in some Corvettes. These M22 units are highly sought-after for performance applications. The term "rock crusher" refers to the noise made by the meshing of the strong-er helical gears in the M22.

These are typically found in 70's GM cars and trucks. This Bellhousing has the correct transmission bolt pattern except for one upper bell housing bolt hole to adapt a 4-speed to an LS-series engine. …

People think the "Rock Crusher" is special or stronger than a standard wide box Muncie. It is special in terms of price but it isn't any stronger. The "Rock Crusher" was built for road racing, with the angle of the gears straightened out to prevent excessive wear in the front bearings due to the forward thrust component of the force vectors ...

GM's goal with the Muncie four-speed was to produce a better shift employing larger synchro cones. He tells us both the M20 wide-ratio and M21 close-ratio transmissions were first offered in 1963. The M22 Rock Crusher would come later to accommodate the heavy twist of Chevrolet's big-blocks in the mid-1960s.

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.

Identifying Muncie 4 Speeds III by Paul Cangialosi : The most popular question has to be that everyone thinks they have the famous "rockcrusher" M22 4 speed. This had the same gear ratios as the M21 but with a heavy duty gearset. The reason you may ask? Well it wasn't designed so that you could go drag racing on Saturday night or impress ...

The Saginaw 4-speed transmission was also used and shown for "M20 PROD V-8 ENG & R.P.O. L30". Easily identified by the reverse gear being on the main case instead of the tail housing.

The front bolt pattern is the consistent GM Muncie / Saginaw four-bolt pattern as found on GM bellhousings and transmissions from the 1940's through the 1990's. The SM420 most commonly has a large, 10-spline output mainshaft for both 2wd and 4wd versions. Some fairly rare 2wd models (likely the 2-ton versions) featured a 35-spline and a male ...

It's $2,000 for an Autogear M22W Super Muncie. Personally I'd rather do that than putting it in and out 4 times to reach the same conclusion. I've also read up quite a bit on the Chevy A833 transmissions. I've sourced …

Step 2. Count the input shaft teeth to find out the make of the transmission. Input shafts differ in each GM transmission, so you can easily identify an M-22 "Rock Crusher by its input shaft count. Each transmission has different numbers of teeth. An M-22 "Rock Crusher" always has 26 teeth.

Also, you need to look at what year transmission you buy if a Muncie regarding input shaft diameter and spline count, output spline count to yoke spline and if …
