TCI 6X Six-Speed Transmissions and Packages

Product images may differ from actual product appearance.

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.

Features:
  • (6) forward gears & fully programmable automatic or manual shifting
  • Improved acceleration and fuel economy at cruising speeds
  • TCI Transmission Control Unit & 4-speed automatic shifter (Ratchet, gate or stock) needed for standard automatic operation
  • Full manual shifting with the 6X Six-Speed requires optional TCI Paddle Shifter or bump switch set-up
  • Self-contained design using 4L80E case eliminates clearance problems of external bolt-on overdrives
  • Compatible with all (stock up to 850 horsepower) Small Block Chevy, Big Block Chevy, GM LS Series, Chrysler and Ford Engines

    Note: Speedometer drive gear and driven gear not included.
