Patent ID: 8613681

Claim:
A hydraulic control system in a transmission, the transmission having a torque transmitting device, the hydraulic control system comprising: a source of pressurized hydraulic fluid for providing a pressurized hydraulic fluid; a first valve in communication with the source of pressurized hydraulic fluid and in communication with a release side of the torque transmitting device, the first valve operable to allow communication of the hydraulic fluid from the source of pressurized hydraulic fluid to the torque transmitting device to release the torque transmitting device; a second valve in communication with the source of pressurized hydraulic fluid and in communication with an apply side of the torque transmitting device, the second valve moveable between at least a first position and a second position, wherein the second valve prevents the hydraulic fluid from communicating with the torque transmitting device when in the first position and wherein the second valve allows the hydraulic fluid to communicate with the torque transmitting device to engage the torque transmitting device when in the second position; and an override feature operably associated with at least one of the first valve and the second valve, wherein the override feature is operable to prevent the first valve from communicating the hydraulic fluid to the torque transmitting device when the second valve is in the second position.
