A slang term for a four-speed transmission, where the gearshift is mounted on the floorboard, instead of on the column. These were very popular in the sixties and it was obvious when someone had one 'cause their right shoulder would dip down when they changed gears; so, while driving my mother's '57 Ford, I would lean down toward the floor and then bend my arm back up and shift the one on the column. Therefore, it appeared that I was one of the cool guys, like James Dean in Rebel without a Cause. Actually, the only thing I had in common with James Dean was that he was in the movies, and I watched them.
