ABSTRACT:
A torque converter including: a pump shell; a cover; and a backing plate for a torque converter clutch fixed by contact with the cover and the pump shell. In some aspects, the backing plate is fixed by axial pressure exerted by the cover and the pump against the backing plate. A torque converter including: a plurality of components axially disposed between a pump shell and a cover; and a pump hub fixedly secured to the pump shell. The position of the pump hub with respect to the pump shell is selected to establish respective axial distances between components in the plurality of components. A torque converter including: turbine shell; and a backing plate for a torque converter clutch, the backing plate rotationally connected to the turbine shell and forming a portion of a boundary between first and second pressure chambers.
