  • Transmission shift system
    Patent number: 7556579
    Abstract: A transmission shift system includes a first control path having a first electrically actuated valve system, and is configured to selectively direct hydraulic pressure to a first plurality of clutches for selecting only an output speed. A second control path independent of the first control path includes a second electrically actuated valve system, and is configured to selectively direct hydraulic pressure to a second plurality of clutches for selecting only an output direction. A shifter has a plurality of switches, each switch being in direct electrical connection with a corresponding of the first electrically actuated valve system and the second electrically actuated valve system for operating the first control path and the second control path controllerlessly, wherein the plurality of switches are operated manually using the shifter.
