  • Patent number: 5342242
    Abstract: An engine output shaft and a transmission torque converter are connected for torque transmission therebetween. A flex plate is disposed between, and secured for rotation with either, the output shaft or the torque converter input shell. The flex plate includes an axially extending rim frictionally engaged with an annular wall secured either the output shaft or the torque converter input shell. A clamp member surrounds the rim on the flex plate radially outward of the annular wall and is selectively tightened to establish a force therein to cause the frictional engagement to be sufficient to transmit the torque.

  • Patent number: 4850829
    Abstract: A transmission pump has a cylindrical body sized to fit in a bore in the transmission housing. Inlets and outlets are circumferentially spaced on the cylindrical body. Convoluted ring type seals are arranged on the outer surface of the body in order to allow the inlets and outlets to have profiles that are closer to or even axially overlap, allowing for greater size within a limited axial body length.
