How do you identify a Muncie M22 Rock Crusher?
How do you identify a Muncie M22 Rock Crusher?
Look for the “GM” sign imprinted on the transmission box to identify the manufacturer of the transmission. Check whether there are any rings around the shaft splines. An M-22 “Rock Crusher” has no rings, so if you see rings in your transmission, it means it is not an M-22 “Rock Crusher.”
How do I identify a Muncie transmission?
There is another way to quickly identify Muncie transmissions. All Muncie transmissions have a ring groove on the input shaft and counter gear. These grooves were cut into the input shaft so the Muncie assembly line worker could easily identify which input shaft should be installed in a particular unit.
What is the difference between a Muncie and a Saginaw transmission?
At a quick glance the Muncie can be easily distinguished from the Saginaw since the reverse lever on the Muncie is mounted on the extension housing of the transmission, whereas on the Saginaw transmission the reverse lever is mounted in the side cover of the transmission.
How do you identify a Saginaw?
The easiest was is by knowing the construction of each unit, and the differences are obvious. If the case and side cover are made of cast iron, that would make it a Saginaw transmission. If it has a cast iron case with an aluminum side cover and tail housing, that will mean you have found a Borg Warner.
Are Rebuilt transmissions as good as new?
Rebuilt transmissions are typically patched with old components; however, they work as you would expect, but the parts are not new ones. While both rebuilt and remanufactured transmissions may be compatible with your vehicle, reman systems are more reliable and higher in quality.
How do I know if my Saginaw is a 4-Speed?
Another quick way to determine a Saginaw is that the shifter arms are all located on the side cover of the transmission case (Muncie reverse arms are located on the tailshaft). GM unit designations for the Saginaw four-speed are M26 or M27.

What kind of transmission did the M22 have?
Another change for the M22 was the new low helical-angle cut gear set which increased the inner strength of the transmission dramatically.
