GM 6L80 BOLT-TOGETHER CONVERTER (2600-2700 RPM)

The innovative TCI® 6L80/6L90 Bolt-Together Torque Converter features a triple-disc lock-up configuration and a bolt-together design that allows for easy disassembly. Removing the billet front provides access to the entire lock-up assembly, turbine, stator and bearings for servicing or restalling for future vehicle modifications. To further enhance strength, TCI® engineers included both a precision-ground billet impeller hub and billet front that are CNC-machined to reduce ballooning, while the billet turbine hub, billet lockup piston and billet clutch hub are pre-hardened.

Triple-Disc Lockup Clutch Handles Stock to BIG Horsepower
This patent-pending converter features a triple-disc lock-up clutch that utilizes woven carbon frictions that withstand the punishment of continuous slip lock-up control. The effective diameter of the clutch in conjunction with the triple-disc configuration provides for significantly higher torque capacity over the stock clutch. The lock-up clutch is attached to an industry-exclusive sprung hub, allowing for smooth engagement while preventing shudder. The sprung hub also absorbs harsh impact loading, which greatly increases transmission life. All of these features work together to provide harder launches without converter lock-up shudder or ECU tuning.

• 7 tenths faster in 1/8 mile on otherwise stock '10 Camaro SS w/ drag radials
• Fully furnace-brazed, computer balanced & hand assembled to precise tollerences
• Billet, bolt-together, self-servicable converter; Easily change stall speed right at home
• NO tuning required; Other converters will hunt RPM, shudder, surge & drive poorly w/o tuning
• Modified engines often burn up stock & aftermarket converters due to their low torque holding capacity; Our design offers substantially increased torque capacity & W.O.T. lock-up capability
