1. A power shift transmission, comprising:
a plurality of clutch valves, each clutch valve actuatable between an open position providing flow to a corresponding clutch pack and a closed position inhibiting flow to the corresponding clutch pack; and
a hydraulic damping rail including:
a primary rail wall defining a primary rail volume;
a rail inlet structured to provide communication of hydraulic fluid between a hydraulic pump and the primary rail volume; and
a plurality of rail outlets, each rail outlet corresponding to one of the plurality of clutch valves and structured to provide communication between the primary rail volume and the corresponding one of the plurality of clutch valves; and
