Zusammenfassung:An electronic transmission range selection hydraulic control system includes a source of pressurized hydraulic fluid, a first mode valve assembly in fluid communication downstream of the source of pressurized hydraulic fluid, a drive clutch actuator connected to a drive clutch and in fluid communication directly downstream of the first mode valve assembly, a reverse clutch actuator connected to a reverse clutch and in fluid communication directly downstream of the first mode valve assembly, a second mode valve assembly in fluid communication directly downstream of the first mode valve assembly, and a park servo connected to the park mechanism and in fluid communication directly downstream of the first mode valve assembly and the second mode valve assembly.
