Abstract

A vehicle having an engine that drives a transmission includes a pump that provides fluid to the transmission and a temperature sensor that monitors a temperature of the fluid. The temperature sensor generates a temperature signal. A control module receives the temperature signal and operates the pump to provide the fluid at a first pressure when the temperature signal is below an upper temperature limit. The control module operates the pump to provide the fluid at a second pressure when the temperature signal is above the upper temperature limit.
