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, 2.23, 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. |
When used with the required TCI® Transmission Control Unit for shift point programming and the optional TCI® Paddle Shifter or bump switch set-up 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 #271600P 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.
