Got big horsepower but still want a six-speed automatic transmission?
Well, here you go. TCI has developed what they say is the world's first six-speed automatic transmission capable of handling up to 850 horsepower for GM applications.
This 4L80E-based unit is a fully programmable unit that gives you six forward gears (2.97, 2.31, 1.57, 1.18, 1.00 and 0.75) for quicker acceleration and increased fuel economy. When used with the required TCI Transmission Control Unit for shift point programming and the optional TCI Paddle Shifter for manual mode gear selection, this trans gives GM-powered vehicles the most functional and modern drivetrain combination on the market.
The TCI 6X Six-Speed Automatic Transmission fits all GM SBC, BBC and LS engines up to 850 hp, has fully programmable shift points, a unique HDT Coating for cooler and more efficient operation, and includes a torque converter, transmission control unit, wiring harness, transmission cooler and dipstick.
