Direct Drive your way to victory lane
Brinn Transmissions Original Transmission is a 2-speed solution to getting the horsepower to the rear tires. The direct drive transmission allows you to remove the bellhousing style clutch assembly and throw out bearing to reduce rotating weight. A low gear ratio of 1.88 to 1 is used when maneuvering through the pits and on to the race track where a 1 to 1 ratio is used to race. The 2.29 to 1 ratio reverse gear does not mesh to any other gears while in either of the forward gears to save even more rotating weight.

Easy Installation and Maintenance
The Original Brinn transmission is the same length as a Borg-Warner or Muncie style transmission so there is no need to change the driveshaft when upgrading. The Original features an external style clutch piston which requires no need in opening the transmission case when servicing. Brinn has designed their transmission to be bench top rebuildable with no special tools needing to be purchased.
