A hydraulic control system for a transmission is provided. The hydraulic control system includes a source of pressurized hydraulic fluid that communicates with an electronic transmission range selection (ETRS) subsystem. In one example, the ETRS subsystem includes an ETRS control valve, a park servo that controls a park mechanism, a plurality of solenoids, and a park inhibit solenoid assembly. In another example, the ETRS subsystem includes an ETRS control valve, an ETRS enable valve, a park servo that controls a park mechanism, a plurality of solenoids, and a park inhibit solenoid assembly.
