Level 10™ High Performance Transmissions, Custom Superchargers & Transmission Rebuilding Kits

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.

Level10™ Performance Torque Converter

With his performance transmissions now working, the big problem became the torque converter; they just couldn 't take the power his race engines were making. Pat's answer to this was to build a bullet proof TH-400 modified to use a clutch instead of a converter. Never satisfied, Pat also modified a converter to handle the power and the racing world took notice. In 1975 Pat was appointed director of the Automatic Transmission Rebuilders Association - Liberty States Chapter. This was nothing short of amazing for a two year old business. Pats work slowly changed from the high performance transmissions to ones that were custom tuned for specific vehicles. Then in 1992 Pat shocked the drag racing world with the first Buick Grand National to run seven second quarter miles.

Level10™ High Performance Transmissions & Custom Superchargers Go International

In 1993 Pat was contacted by Bin Sulayem Performance, the largest aftermarket supplier in the Middle East. He began producing special purpose performance transmissions to their specifications for the MBS Expeditions and continues this to this day.

In 2001 Pat stepped into the road racing world and once again set the standard when he teamed up with Lexus. He developed a manual shift automatic that won the Rolex Cup in 2002. They have so many wins in so many different kinds of racing events; it is difficult to keep count.

In 2003 Level10 began development for diesel trucks, with proven packages now available to handle the ground shaking torque of these monsters. That kind of innovation continues to this day with constant testing and improvement. Pat will never be satisfied, always looking for a little more speed, a little less friction, a little more strength, and better power transfer. And don't forget the one who benefits the most from all this effort... you!
