Chevy 3-speed overdrive

The first of the Chevy 3 speed OD transmissions came out in 1955 and it was a 12 volt car. Pontiac and the Chevy 3100 and GMC 100 series trucks were using the same transmission. There were four different gear combinations in them and the OD unit gave a 24% step up in output. Parts are available even today.
