Background
The M6 Presto-Matic was a Chrysler Corporation semi-automatic transmission produced from 1946 to 1953. It was a special manual transmission with a fluid coupling. Although it had just two forward gears, an electric overdrive unit was attached and useful in either gear for a total of four forward speeds.
