Abstract

A method and apparatus for controlling transmission oil temperature are provided. The transmission oil is heated using a motor coil of an electric oil pump (EOP) as a heater before a startup of a vehicle. The method includes applying a current to the motor coil of the EOP configured to operate a transmission of the vehicle to thus heat the transmission oil by heat generated from the motor coil.
