  • The Street Machine Standard - TCI StreetFighter Transmissions are the industry standard transmission choice for high horsepower, street-driven vehicles with 400-675 HP. Specially selected quality components ensure less slippage and faster shifts.
  • Faster Shifts = Lower ET's - The StreetFighter Transmission features a manual/automatic valve body, allowing you to manually shift the vehicle or to allow automatic shifting functionality by placing the shifter in the Drive Position. Automatic shifting delivers racetrack shifts, shaving time off your ET's.
  • Quality Components, Improved Lubrication, Higher Line Pressure - StreetFighter Transmissions are equipped with special clutches and bands, along with new sprags/roller clutches for increased torque capacity. Higher line pressure delivers extra firm shifts and torque capacity, while improved lubrication increases fluid sent to planetaries and internals.
  • The Best Quality - All TCI Transmissions feature a breakthrough Heat Dissipating Technology Coating for the best dissipation in heat in the industry. Transmissions are Triple-Tested to meet strict quality standards
  • Made in Ashland, Mississippi, USA


This C6 Transmission is equipped with TCI StreetFighter components to handle up to 675 HP from Ford 289/302/351C/351W engines.

We bought this trans 4 years ago. First they shipped a small block pattern c6 which we had to return. The install took about a year as it was combined with a new 460 and other modifications to the car. When we took it in the test drive it turned out again, they’d shipped the wrong trans again-with a reverse manual valve body instead of regular. The tech gave me crap about adjusting the vacuum modulator being the problem, something that adjusts shift firmness, not its ability to shift at all. Shortly after that the warranty was up they said they’d ship the correct valve body out, then later said they don’t do that. I sourced a factory Ford valve body and shift kit but never got to install. When dropping the fluid on a trans that had less than 1,000 street it was absolutely full of aluminum and steel as seen in the pictures. The tci converter is likely the cause. tci will do absolutely nothing unless i ship out across the country again and pay them to rebuild it. Absolutely no thanks. I dropped a core c6 off at the local shop to have built and a converter built from Portland.Avoid TCI like the plague.
