    Designed with the latest drivetrain technology developments, TCI's 6X six-speed automatic transmission has six forward gears (2.97, 2.23, 1.57, 1.18, 1.00, 0.75) for quicker acceleration, and increased cruising speed fuel economy Featuring a compact design, this versatile 6X six-speed automatic transmission is able to handle up to 850 HP, and fits Small Block Chevy, Big Block Chevy and GM LS Series engines that includes Pro Touring, street or race vehicles. This TCI 6X six-speed automatic transmission is considered the most functional and modern drivetrain combination on the market when used with a TCI EZ-TCU Transmission Control Unit and TCI Paddle Shifter or Outlaw 2-Button Shifter setup for manual mode gear selection.

    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. Each TCI 6X Six-Speed transmission utilizes the patented HDT Coating for cooler operating temperatures and improved drivetrain efficiency.

    Individual Bellhousings and Bellhousing Kits (containing bellhousing, and matched flexplate, crank adapter and necessary hardware), along with TCI Paddle Shifters and Outlaw Shifters are available separately or included in a transmission package.

    TCI 6X Six Speed Transmission Packages do not contain torque converters. Torque converters must be ordered separately, based on your application's stall speed requirements.
