ABSTRACT:
A valve assembly in a fluid system of an automatic transmission for controlling the lock-up of the torque converter assembly of the automatic transmission includes a regulator valve for establishing a pressure level of fluid flow from a fluid source, a torque converter control valve for controlling fluid pressure to the torque converter assembly during the disengagement operating mode, and a lock-up valve receiving fluid pressure feedback from the torque converter control valve to close a fluid path during the disengagement operating mode and opening the fluid path for allowing fluid pressure to the apply side of the torque converter assembly during the engagement operating mode.
