Abstract
Vehicles, transmissions for vehicles, and methods of operating transmissions are envisioned. A vehicle includes a chassis, a plurality of wheels coupled to the chassis, and a transmission mounted to the chassis. The transmission includes at least one torque-transmitting mechanism selectively engageable in response to one or more fluids pressures applied thereto, a first pump to selectively deliver fluid pressure to the at least one torque-transmitting mechanism at a first pressure, a second pump to selectively deliver fluid pressure to the at least one torque-transmitting mechanism at a second pressure greater than the first pressure, and an electro-hydraulic control system to control delivery of fluid pressure from the first and second pumps to the at least one torque-transmitting mechanism in a plurality of operating modes of the transmission.
