Description: The B&M Hydro Stick became the only patented four-speed automatic racing transmission in history when it launched in 1961. Based on the popular Hydramatic line of transmissions, the B&M Hydro Stick allowed racers to manually shift their automatic transmissions. In a time when manuals ruled the track, B&M’s Hydro Stick changed the game by making it possible to keep an automatic transmission in low gear until the driver decided to upshift.
