Hydraulic control system for an automatic transmission having a three path torque converter control subsystem
A hydraulic control system for a transmission includes a first source of pressurized hydraulic fluid for providing a first flow of hydraulic fluid, a second source of pressurized hydraulic fluid for providing a second flow of hydraulic fluid, and a torque converter control subsystem for controlling a torque converter and a torque converter clutch. The torque converter control subsystem includes a torque converter control valve and a solenoid. The solenoid is multiplexed to the torque converter control valve and the torque converter clutch. The torque converter control valve is operable to control a flow of hydraulic fluid to the torque converter and to other subsystems within the hydraulic control system.
