Nov 08, 2016 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.

Nov 09, 2014 ALL the Muncie car 4 speeds are aluminum case-no exceptions. The preceding Saginaw 4 speed was iron cased. The 63-65 M20 has a 2.56:1 first gear, the later M20's are 2:52:1. The 63-65 also have a 7/8 cluster gear shaft while the rest are 1 . While perhaps not much desired for off road they do work as well as the T90A.
