angle, giving the M22 the nickname "RockCrusher." I believe the reasons for bringing the T10 to the Muncie plant were threefold. First was to revamp the T10 to handle more power. Second was the direct benefit of the increased sales volume of the 4-speed GM muscle car market. The third reason was increased T10 royalty benefits. Muncie Design Changes

Since the gears are "farther" apart, 1st gear is lower than the M21/M22 making it easier to get the car moving. Experience......
