Torque Converter 1 Impeller 2 Freewheel clutch 3 Stator shaft 4 Input shaft 5 Stator 6 Turbine 7 Lockup vibration damper 8 Lock-up clutch piston 9 Converter housing cover The torque converter is the coupling element between the engine and the gearbox and is located in the bell housing, on the engine side of the transmission. The driven power from the engine crankshaft is transmitted hydraulically and mechanically through the torque converter to the transmission. The torque converter is connected to the engine by a drive plate. The torque converter comprises an impeller, a stator and a turbine. The torque converter is a sealed unit with all components located between the converter housing cover and the impeller. The two components are welded together to form a sealed, fluid filled housing.
