ABSTRACT:
A rotary switch, used to select the operating range of an automatic transmission, controls solenoid-operated valves corresponding to the selected range to open and close a connection between a range valve assembly and a control pressure source. A forward range selection electric circuit includes a forward range high side driver, a solenoid-operated control valve, the rotary switch, a power source, and a current monitor. There is a similar circuit for the reverse range. A forward range valve and reverse range valve respond to control pressure produced by the circuit to open a fluid pressure source to a line that is pressurized to produce forward drive, a second position opens a connection between the fluid pressure source and a line that is pressurized to produce reverse drive and vents those lines to sump.
