Level 10 got started back in 1971. Pat Barrett worked out of his home garage and realized early on the best way to go fast was to make the most of the available horsepower. Unfortunately, the transmissions of the day just were not up to the task. Pat began experimenting with valve bodies and clutches and soon had a strong, fast, shifting, slip-free high performance transmission. The word began to spread and he opened his first dedicated shop in 1973.
