TCI StreetFighter transmissions are durable enough to withstand the rigors of even the toughest street machines. Equipped with a 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. In either mode, you get a race track shift that bangs through the gears and shaves time off of your ETs. When you use the manual gear selection feature, the StreetFighters upshift and downshift right when you move the lever, with no lag or governor override. When you select the normal drive position, they retain positive automatic shifts for the ease of driving you look for in an automatic transmission.
