Patent ID: 7556579

Claim:
A transmission shift system for a transmission having a first plurality of clutches for determining only an output speed of said transmission and a second plurality of clutches for determining only an output direction of said transmission, wherein said first plurality of clutches and said second plurality of clutches are hydraulically actuated via hydraulic pressure from a hydraulic pressure source, said transmission shift system comprising: a first control path in fluidic connection with said hydraulic pressure source, said first control path including a first electrically actuated valve system including a first solenoid value pair configured to selectively direct said hydraulic pressure to said first plurality of clutches for selecting only said output speed; a second control path in fluidic connection with said hydraulic pressure source, said second control path including a second electrically actuated valve system and being configured to selectively direct said hydraulic pressure to said second plurality of clutches for selecting only said output direction, said second control path being independent of said first control path; and a shifter having a plurality of switches, each switch of said plurality of switches being in direct electrical connection with a corresponding of said first electrically actuated valve system and said second electrically actuated valve system for operating said first control path and said second control path controllerlessly, a first subset of said plurality of switches being in direct electrical connection with said first solenoid pair to controllerlessly operate said first solenoid valve pair, wherein said plurality of switches are operated manually using said shifter.
