A hydraulic clutch assembly can include a shaft defining a shaft channel, one or more hydraulic ports defined through the shaft, and one or more lubrication holes defined through the shaft. A porting manifold can be disposed at least partially within the shaft channel. The porting manifold can include a control pressure path in fluid communication with the one or more hydraulic ports and a lubrication flow path in fluid communication with the one or more lubrication holes. The control pressure path and the lubrication path can be fluidly isolated in the porting manifold.
