A hydrodynamic torque converter having a converter housing defining interior space for receiving a converter work fluid, a turbine wheel arranged in interior space of the converter housing and rotatable with respect to the converter housing, a lockup clutch having a coupling element axially displaceably arranged on the turbine wheel for selectively coupling the turbine wheel with the converter housing. The converter housing and the coupling element define a pressure fluid space capable of being filled with a pressure fluid. The interior space is separated from the pressure fluid space for preventing fluid communication between the interior space and the pressure fluid space. The hydrodynamic torque converter also has a first channel connected to the interior space for guiding converter work fluid into the interior space, a second channel connected to the interior space for guiding converter work fluid out of the interior space and a third fluid channel connected to the pressure fluid space for selectively directing pressure fluid into and out of the pressure fluid space. The coupling element is displaced for at least partially canceling a rotational coupling of the converter housing and the turbine wheel when pressure fluid is directed into the pressure fluid space.
