Claim:
1. A hydrodynamic torque converter comprising: an impeller having a rotational axis and comprising an impeller shell having a first engagement surface; a turbine-piston coaxially aligned with and hydrodynamically drivable by the impeller, the turbine-piston comprising a turbine-piston shell comprising a turbine-piston flange having a second engagement surface facing the first engagement surface of the impeller shell, the turbine-piston being movable axially toward and away from the first engagement surface to position the torque converter respectively into and out of a lockup mode in which the turbine-piston is mechanically locked to so as to be non-rotatable relative to the impeller shell; an annular lockup resistance member comprising an annular elastomeric sandwich washer coaxially aligned with the rotational axis and disposed between the impeller shell and the turbine-piston shell so as to resist axial movement of the turbine-piston toward the first engagement surface and into the lockup mode, the annular elastomeric sandwich washer comprising
