Show original supplier description
The TCI 371150 Super StreetFighter Transmission is a performance automatic transmission designed to bridge the gap between streetable and full competition units. Intended for normally aspirated vehicles, it can handle engines producing up to 875 horsepower, with specific 4L60E applications rated for up to 750 HP in 4th Gen F-Body vehicles. This transmission features a TCI Constant Pressure Valve Body, ensuring firm clutch and band application to eliminate slippage and optimize performance. It provides both manual and automatic shift options, allowing drivers to choose between performance-oriented shifting for the strip or easier driving for the street. The case is constructed from aluminum, and it includes a slip-on yoke style connection. Key specifications include four gears, an automatic/manual valve body, and a first gear ratio of 3.06:1. It is not SFI-approved, and a torque converter is not included. For non-stock applications, TCI's TCU System is required for operating transmission and torque converter functions. The transmission is shipped without a TCI speedo driven gear or housing.
