As the world’s first aftermarket 6-speed automatic transmission capable of handling 850 HP, you better believe this is an amazing piece of engineering! The TCI® 6x Six-Speed™ Automatic Transmission 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. This versatile transmission fits Chevy Small Block, Big Block and LS Series engines and features a compact design allowing it to work in a variety of vehicle applications including Pro Touring, street or race vehicles. 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, you get the most functional and modern drivetrain combination on the market for your vehicle.
To ensure durability, TCI® engineers run each transmission across a 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 6x Six-Speed Automatic Transmission utilizes the patented HDT Coating™ for cooler operating temperatures and improved drivetrain efficiency.
This transmission comes with bellhousing only. All 6x Six-Speed™ Transmissions come with the 1997 & later GM LS engine transmission case, which will fit LS or any conventional GM/Chevy engines.
