TCI 4L80E Bolt-Together Torque Converters

TCI 4L80E bolt-together torque converters are high-stall, multi-disc, lock-up torque converters with new components designed specifically for applications utilizing electronic overdrive transmissions. Each converter's high-stall nature gets the engine to maximum torque and multiplies it as the vehicle starts to move. This improves vehicle launch and overall performance.

These TCI converters feature a triple-disc, lock-up assembly with woven carbon frictions to handle more torque and dissipate heat more efficiently than the stock component. Designed with a higher clamping force on the clutch friction than stock and competitor options, the converters also boast full wide-open-throttle lock-up capability. Featuring a CNC-machined, billet bolt-together design, there is no welding or cutting required to access internals, meaning that each unit can be unbolted and disassembled, enabling easy stall changes and rebuilds, as well as efficient replacement of bearings and lock-up components.
