  • Transmission control apparatus
    Patent number: 6695748
    Abstract: An electrohydraulic transmission control apparatus (10) that produces, controls and directs hydraulic pressure inputs to the clutches, brakes and shift mechanisms of an automatic transmission to shift the transmission. A module body (14) supports control apparatus components and is removably mountable to a transmission housing (16) of the transmission. The module body (14) defines a plurality of fluid conduits (28). A plurality of control valves (26) is disposed on the module body (14) and meter hydraulic fluid through the conduits (28) to brake and clutch hydraulic cylinders and shift mechanisms in the transmission. A plurality of solenoid-operated control valves (26) is also disposed on the module body. A controller (34) disposed on the module body is connected to the solenoids (30) and controls the valves by operating the solenoids (30) in accordance with inputs received from sensors (36-44) that detect various factors representing the running state of the transmission and the vehicle it's mounted in.
