TCI® Torque Converters for GM 6L80E Transmissions are fully serviceable and purpose-built to improve launch and overall performance. This converter can be completely disassembled and serviced. Removing the billet front provides access to the entire lock-up assembly, turbine, stator and bearings.

These converters feature a triple-disc lock-up assembly which can easily be disassembled for servicing. They also include high-speed, load-rated Torrington bearings. A deep-groove ball bearing on the turbine spline reduces friction and increases the high-speed stability of converter components along with providing input shaft support. The precision-ground billet impeller hub and billet front are CNC-machined to reduce ballooning, while the billet turbine hub, billet lockup piston and billet clutch hub are pre-hardened to improve strength. Easy stator changes and modifications can also be made when the unit is unbolted. By purchasing additional pump assemblies and stators, stall changes can be performed without machining the converter open. TCI® Torque Converters for GM 6L80E Transmissions also feature a higher lockup clutch torque capacity and higher torque multiplication than stock, along with a higher friction surface area than competitors’ converters and include three different stall speeds (2600-2700, 2800-2900, 3100-3200).

All of these features work together to handle harder launches. Special oil slots in the turbine hub and impeller flange increase oil flow and reduce operating temperatures. Each converter also includes woven carbon friction material designed specifically for GM constant slip applications.

As with all TCI® torque converters, these feature proprietary HDT (Heat Dissipating Technology™) Coating™, which enables cooler operating temperatures and more efficient drivetrain operation. Each TCI® converter is also built to exact specifications and is Triple Tested during assembly. Triple Testing includes run-out testing, leak testing and computer balancing. TCI® Torque Converters for GM 6L80E Transmissions are fully furnace-brazed, computer balanced and hand assembled to precise tolerances.
