Abstract
The present invention provides a torque converter support for an automatic transmission which uses a driving gear of a fluid pump to support the torque converter. The driving gear is supported by a journal area of the fluid pump. The torque converter impeller hub, attached to the torque converter, is engaging the driving gear and has at least one rib therearound. A hollow bore of the driven gear rides against the rib, offering structural support to the torque converter impeller hub and torque converter. The driven gear also has a hub. The hub has an outer surface which rides against the journal area and provides the base support for the system.
