TCI 6X Six Speed Transmission Package; Pontiac Bellhousing & Outlaw™ Shifter TCI-271701P18

Using the latest developments in drivetrain technology, TCI® has developed an innovative automatic transmission for Pro Touring, street and all-out race vehicles. Designed for Pontiac applications, this 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. Capable of handling up to 850 horsepower, this versatile transmission from TCI® features a compact design, allowing it to work in a variety of performance applications.

When used with the included EZ-TCU™ for shift point programming and the included Outlaw™ 2-Button Shifter set up for manual mode gear selection, or optional TCI® Paddle Shifter, this automatic transmission gives vehicles the most functional and modern drivetrain combination on the market.

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 TCI® transmission utilizes the patented HDT Coating™ for cooler operating temperatures and improved drivetrain efficiency.
