Nick name for a
transmission made in the early
seventies used in high performance
General Motors cars.
The Muncie M22 as it was really called, was a very tough, close ratio, four speed, manual transmission.
It had straight cut gears that gave it a whining sound.
The gear ratios were: 2.20 / 1.64 / 1.28 / 1.00 / 2.27
