Got a 1969 M22 tranny. I've heard that the M22's are straight-cut gears--thus requiring no clutch when up shifting... Myth or Fact?? Also, will a shifter assem. from a 1971/72 fit on the tranny?

Also, if you have a 1969 original 4 speed, PM me your #s and I will check to find out if it matches. (would really like to get this back to the owner)..


Thanks..

Myth. They are straighter cut than M21 or M20s, but not perfectly straight. I estimate ~25° vs. 45°.

JEEEEEEEEEEEEEEEEEEEEEEESUS!!! No, shifting an M-22 has ABSOLUTELY nothing to do with the angle of the gear teeth. NONE WHATSOEVER! The lower angle of the gear teeth in an M-22 makes the gears more durable, thus stronger.
The shifting, or changing from one gear to another, occurs between the sliding outer ring of the synchronizer and a row of small teeth on each gear. This row of small teeth on each gear, as well as the synchronizer assembly, is 100% IDENTICAL in all factory Muncies. Thus, there is no difference in shifting characteristics between ANY Muncie.

The 68-72 factory Muncie shifters installed in Chevelles are the same. The factory shifters sort of will and sort of won't bolt up to a Muncie 4sp. The reason is because a portion of the factory shifter is attached to the tranny cross member and a portion of it attaches to the tranny. But regardless, you DO NOT want one of the original shifters. With age and use, they became worn, sloppy and a real headache.
