The torque converter is the link between the engine and the gearbox. It is located in the gearbox housing on the engine side. Drive power from the crankshaft of the engine is transmitted hydraulically and mechanically through a torque converter to the gearbox. The torque converter is connected to the engine through the drive disc.

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

The torque converter contains a hydraulically operated 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 applied to the clutch. The TCM can apply 3 torque converter operating modes: unlocked, partially locked, and fully locked.
