TCI offers the perfect solution for street cruisers who want excellent street performance and long lasting durability. Using the highest quality TCI manufactured components, each Street Rodder package is equipped with an automatic valve body and Valve Body Performance Improvement Kit that allow you to achieve firmer, yet not too harsh shifts in the vehicle while remaining fully automatic and retaining the stock shift pattern. Horsepower figures range from 350-525 HP, dependent on the application. Each Street Rodder Transmission and Torque Converter undergo the industry-recognized Triple Testing to verify that internal fluid pressures and shift characteristics match the strict TCI quality control standards. Torque converters are tested to maintain that the impeller body and pump drive hub remain true and are then pressurized and lead tested to confirm the integrity of the weld seams. Finally, each unit is computer balanced to reduce drivetrain vibrations that can cause serious damage to your converter.
