TCI Automotive® has introduced an easy-to-service, high-horsepower, triple-disc torque converter for 4L80E transmissions.  

The 4L80E Triple-Disc, Bolt-Together Torque Converter is designed for durability, DIY service and stall speed changes. There’s no need to ship it back to TCI®, no welding and no cutting required. Inside is a triple-disc lock-up clutch with the latest generation carbon friction material with significantly higher torque capacity than commonly found in other aftermarket converters – more than 1,000 HP. CNC-billet construction provides increased strength over traditional stamped steel converters, while a furnace-brazed impeller and turbine and tig-brazed turbine fins add to durability. It is also finished in the TCI® HDT Coating™ to prevent corrosion and dissipate heat. 

Available in either a 3,000-3,200 RPM or custom stall speed option, the TCI® Triple-Disc, Bolt-Together Torque Converter for GM 4L80E Applications is made specifically for the 4L80E, TCI® 6x Six-Speed™ and TCI® 4x Four-Speed™ electronic transmissions. It not only offers easy servicing, but its increased clutch torque capacity allows for wide-open throttle lock-up in high-horsepower engines.
