C6 StreetFighter Transmission for 1966 and Up Ford FE (332-428) Engines

TCI StreetFighter Transmissions are designed to withstand the rigors of
 street machines ranging anywhere from 400 to 675 horsepower with a 
non-supercharged system using pump gasoline, depending on application. 
Equipped with a TCI manual/automatic valve body, most units allow you to
 manually shift the vehicle into each gear change or, by placing it in the
 drive position, remain fully automatic. This gives you racetrack 
shifts and shaves time off your ETs. TCI 700R4, 2004R and AOD 
StreetFighter Transmissions also feature a TCI Constant Pressure 
Valve Body to ensure that clutches and bands are applied firmly to 
eliminate slippage.
