The economical TCI Street Rodder is ideal for vehicles that are powered by engines producing 350 to 450 horsepower, depending on the application. This makes it perfect for a mild daily driver or street rod. Every Street Rodder Transmission is equipped with a TCI automatic valve body and a Valve Body Performance Improvement Kit to allow a firmer, yet not too harsh shift in the vehicle while remaining fully automatic. Street Rodders retain the stock shift pattern and feature increased thrust capacity and more torque capacity with less slippage than OE transmissions.
