Abstract

A transmission system is provided. The transmission system includes an electric motor rotationally coupled to a first pump, a second pump, and a third pump via a drive shaft, where an output of the first pump is in fluidic communication with a lubrication circuit and where an output of the third pump is in fluidic communication with an actuation circuit. The transmission system further includes a valve fluidly coupled to the output of the first pump and an output of the second pump and a controller including instructions stored in non-transitory memory that when executed during a first operating condition, cause the controller to selectively operate the valve based on a change in one or more operating conditions in the transmission system.
