The torque converter is the connection between the engine and the gearbox. It is located in the gearbox housing on the engine side. The drive power from the engine crankshaft is transmitted through the torque converter to the gearbox using hydraulics and a mechanical system. The torque converter is connected to the engine via a drive disk.

The main components of the torque converter are the pump wheel, stator and turbine wheel. The torque converter is a sealed device, and all its parts are located between the torque converter housing cover and the pump wheel. Both of these elements are welded to each other, forming a sealed liquid-filled housing. Since the pump wheel is welded to the torque converter housing cover, it rotates at the speed of the engine crankshaft.

The torque converter contains a hydraulically controlled lock-up clutch, which is controlled by the TCM via a solenoid valve in the valve block; it activates spool valves to control the hydraulic pressure supplied to the clutch. The TCM can apply 3 modes of operation of the torque converter: unlocked, partially locked and fully locked.
