ABSTRACT:
An electronic transmission range selection (ETRS) system for shifting a transmission range of a transmission includes a park servo valve movable between a first position to inhibit a first flow of pressurized fluid and a second position to enable the first flow of pressurized fluid. A hydraulic servo assembly is movable between a first position and a second position based on the first flow of pressurized fluid. An actuator arm is interconnected to the hydraulic servo assembly. When the hydraulic servo assembly moves to the second position the actuator arm shifts the transmission range from a Park position to an Out-of-Park position.
