GF27.20-P-2010AHK Torque converter component description
- Transmission 722.904/906/907/999

Component Identification:

Location
The torque converter is bolted to the driven plate in the torque converter housing and installed in the transmission bell housing.

Task
When the vehicle is stationary and at idle speed, the torque converter reduces the power flow between the engine and transmission to a minimum and multiplies engine torque and continuously adapts rpm and torque when the vehicle is driven off.

Component Identification:

The impeller is connected to the engine, the turbine wheel is connected to the transmission input shaft. The stator is connected to the transmission housing via a freewheel and the stator shaft.

Function
The impeller delivers oil through the impeller blades as a result of centrifugal force outwards to the turbine wheel and drives it. The turbine wheel blades direct the oil onto the blades of the stator, which in turn pushes the oil to the impeller. A torque increase occurs due to this reversal at the stator which is supported against the transmission housing via the freewheel.

Torque conversion reaches its highest value when the rpm difference between the impeller and turbine wheel is at a maximum.

The oil in the torque converter is constantly being replaced so that the heat produced in the operating phase can be dissipated via the transmission oil cooler.

As of this operating condition, also called the coupling point, the stator turns with the impeller and the turbine wheel.
