Abstract:
1. A hydraulic control system for a transmission comprising: a source of pressurized hydraulic fluid; an accumulator subsystem in downstream fluid communication with the source of pressurized hydraulic fluid, wherein the accumulator subsystem includes an accumulator in communication with a first one-way valve and an accumulator solenoid, wherein the first one-way valve and the accumulator solenoid are disposed in parallel to one another; a clutch solenoid having an inlet in downstream fluid communication with the accumulator subsystem and the source of pressurized hydraulic fluid; a clutch actuator in downstream fluid communication with the clutch solenoid and the accumulator subsystem; a first fluid flow path defined as fluid communication from the source of pressurized hydraulic fluid through the clutch solenoid to the clutch actuator; and a second fluid flow path defined as uninterruptible fluid communication from the accumulator subsystem to the clutch actuator and to the inlet of the clutch solenoid, wherein the second fluid flow path is disposed in parallel to the first fluid flow path.
