6x Six-Speed

Using the latest developments in drivetrain technology, TCI® has developed an innovative automatic transmission for Pro Touring, street and all-out race vehicles. Designed for GM SBC, BBC, LS and Pontiac applications, as well as Fords and Chryslers, the 4L80E-based TCI® 6x Six-Speed Automatic Transmission is a fully programmable transmission that gives you six forward gears (2.97, 2.23, 1.57, 1.18, 1.00, 0.75) for quicker acceleration and increased fuel economy at cruising speeds and is capable of handling up to 850 horsepower.
These versatile transmissions from TCI® feature a compact design, allowing them to work in a variety of performance applications. Originally designed for GM applications, TCI® now offers complete kits available for Ford, Chrysler and Pontiac engines.
When used with the required TCI® EZ-TCU™ Transmission Controller and harness for shift point programming and the optional TCI® Paddle Shifter or Outlaw™ 2-Button Shifter set-up for manual mode gear selection, this automatic transmission gives vehicles the most functional and modern drivetrain combination on the market.
To ensure durability, TCI® engineers run each transmission across a hydraulic tester valve body dyno and computer-controlled transmission dyno to ensure proper line pressures and top notch transmission performance. Proof of this Triple Testing process is included with each transmission, shipped in the form of individual serialized spec sheets containing test scores. In addition, each TCI® transmission utilizes the patented HDT Coating™ for cooler operating temperatures and improved drivetrain efficiency.
