This transmission has been designed for street performance and other applications where tire spinning shifts are desired. The street/strip transmission contains racing components which increase strength, reliability, and torque capacity.
Before beginning the rebuild, each unit is closely inspected for abnormal wear. Many components are automatically replaced, even if normally passed over by other manufacturers; all friction material is upgraded, lube circuits are modified, and the valve body is re-worked to achieve more positive shifts and better durability.
