I am having a disagreement with a friend of mine on Muncie transmissions. HE IS TRYING TO TELL ME THAT THE M20 M21 AND M22 WERE ALL AVAILABLE with wide or close ratios. I always thought that the m20 was wide ratio and the m21 and m22 were close ratios. To settle an argument can someone tell me who is right? Thanks very much for any input.

Your right. He does not know what he is talking about. M21 and M22 are the options code for the close ratio versions. M20 is the base 4-sp.

M20 - 4-sp Wide-Range
M21 - 4-sp Close-Ratio
M22 - Special 4-sp Close-Ratio
