1. A vehicle comprising:
a drive wheel;
an electric machine configured to deliver and receive mechanical power to and from the drive wheel;
a battery;
an inverter having an input connected to the battery and an output connected to the electric machine, and configured to convert power between DC electrical power at the input and AC electrical power at the output;
a gearing arrangement of a transmission disposed between the electric machine and the drive wheel;
a pump configured to circulate lubricating fluid within the transmission;
a voltage controller configured to deliver DC electrical power from the inverter to the pump; and
a vehicle controller programmed to, in response to the drive wheel powering the electric machine to generate AC electrical power and the electric machine delivering AC electrical power to the inverter during a towing condition of the vehicle, operate the voltage controller to power the pump.
