An hydraulic pressure control system in the hydrostatic system of a split torque transmission uses a shunt circuit to redirect hydraulic fluid in a loop between a first pump and a second pump or motor. The shunt is opened by restricting a variable area or valve in the primary loop and opening a variable area or valve in the shunt. Adjusting the openings of the valves prevents overloading of the engine, lugging under instantaneous loads and overspeed due to backloading.
