Claim 6:
7. A vehicle system, comprising:
a tandem axle coupled to a drive shaft and including a first axle and a second axle;
an axle sump fluidically coupled to the tandem axle;

a first oil passage selectably coupling the external reservoir to the axle sump via an electric pump;
a second oil passage selectably coupling the external reservoir to the axle sump via an electric valve; and
a controller including instructions stored in non-transitory memory that, when executed, cause the controller to:
decrease an oil level in the axle sump in response to the tandem axle transitioning from a first configuration to a second configuration;
