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.

Using the latest developments in drivetrain technology, TCI has developed an innovative automatic transmission for Pro Touring and Street Performance vehicles. Designed for GM LS Engine applications, this 4L60E-based TCI 4x Four-Speed Automatic Transmission is a fully programmable transmission that gives you four forward gears (3.06, 1.63, 1.00, 0.7) for quicker acceleration and increased fuel economy at cruising speeds. By utilizing the 4th gear overdrive ratio and having the ability to lock up the torque converter, you can have the best of both worlds. Use a high stall converter at launch then lock it up on the highway to bring those rpms down when you just want to cruise.

Capable of handling up to 500 ft lbs of torque, this versatile transmission from TCI features a compact design, allowing it to work in a variety of performance applications. When used with the EZ-TCU for shift point programming, this automatic transmission gives vehicles one of the most functional and modern drivetrain combination on the market. "EZ" is the key as you will have the ability to tune the transmission on the fly by using a very simple phone app for both Android and Apple.

To ensure durability, TCI runs each transmission across a computer-controlled transmission dyno to ensure proper line pressures and top-notch transmission performance.
