TCI Super StreetFighter Transmissions
TCI Super StreetFighter transmissions bridge the gap between the StreetFighters and full Competition series transmissions. Like the StreetFighter units, these are equipped with 100 percent tested, manual/automatic valve bodies. That means that most units allow you to manually shift the vehicle into each gear change or, by placing it in the drive position, remain fully automatic. In either mode, you get a racetrack shift that bangs through the gears and shaves time off your ETs. When you use the manual gear selection feature, the Super StreetFighters upshift and downshift right when you move the lever, with no lag or governor override. When you select the normal drive position, the transmissions retain positive automatic shifts, for the ease of driving you look for in an automatic transmission.
