ABSTRACT:
A system and method for substantially simultaneously shifting the speed of a plurality of multiple-speed motors that have shifting valves. The system and method includes substantially simultaneously applying an equal shifting force to all shifting valves, resisting shifting of all shifting valves with an equal biasing force arising from deflection of springs contained in springs chambers, and fluidly communicating all spring chambers with a common receptacle to equalize the pressure in all spring chambers.
