Not sure how this one slid past us, but TCI is offering a six speed automatic transmission based on the GM 4l80E. This is rated to a claimed 850 hp and is intended for everything from street machines to full-on race cars.
Right now it’s only available for GM V8 applications but with the right adaptors, we think you could find a home for it anywhere you wanted to.
Read up on this thing and start thinking about actually running those 4.56 gears on the street now!
TCI® 6x Six-Speed Automatic Transmission
Transmission technology leader develops the world’s first 6-speed automatic transmission capable of handling up to 850 horsepower for GM applications
Using the latest developments in drivetrain technology, TCI® has recently developed an innovative automatic transmission for Pro Touring, street and all-out race vehicles. Designed for GM SBC, BBC and LS applications, the 4L80E-based TCI® 6x Six-Speed Automatic Transmission is a fully programmable transmission that gives you six forward gears (2.97, 2.31, 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.
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 automatic transmission gives GM powered vehicles the most functional and modern drivetrain combination on the market. This innovative transmission design is also available in a GM performance drivetrain package that includes the TCI® 6x Six-Speed Transmission, transmission control unit, paddle shifter, wiring harness, transmission cooler and dipstick.
To ensure durability, TCI® engineers run each transmission across a computer-controlled transmission dyno to assure 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. These versatile transmissions from TCI® feature a compact design, allowing them to work in a variety of performance GM applications. In addition, each TCI® transmission utilizes the patented HDT Coating™ for cooler operating temperatures and improved drivetrain efficiency.
