Abstract:
A torque converter including a cover, a turbine pump in fluid contact with the turbine, and a pump shell connected to the cover. The torque converter includes a pump hub connected to the pump shell such that the pump shell and the pump hub are fixed with respect to rotation. The pump hub also includes a portion with a distal end having a plurality of indentations and a plurality of sloped surfaces in contact with the plurality of indentations. The plurality of sloped surfaces is arranged to receive a plurality of protrusions for a transmission pump gear and to urge the pump hub or the pump gear into rotational motion to urge the plurality of protrusions into mating engagement with the plurality of indentations.
