Torque Converter Components - TdV6 Models
The torque converter is the coupling element between the engine and the gearbox and is located in the transmission
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. With the impeller welded to the converter housing cover, the impeller is therefore driven
at engine crankshaft speed.
The converter housing cover has threaded bosses which provide for attachment of the engine drive plate which is
connected to the engine crankshaft. The threaded bosses also provide for location of special tools which are required to
remove the torque converter from the bell housing.
