A transmission park-brake system includes a transmission park brake, a solenoid, first, second and third pressure sources, and a servo valve for disengaging the park-brake using the first and second pressure sources, holding the park-brake disengaged using a force produced by the solenoid and one of the first and second pressure sources, and engaging the park-brake using the third pressure source.
