Circuit/System Description

The transmission contains two electric drive motors and an auxiliary transmission fluid pump. The drive motor motors and auxiliary transmission fluid pump are cooled by the transmission fluid. Hot fluid exits the drive motor motors and auxiliary transmission fluid pump housing and flows to the transmission cooler supply line. The supply line connects to the cooler. From the cooler, the fluid returns through the oil cooler return line and enters the lubrication circuits. A non-serviceable motor temperature sensor is located in each drive motor assembly.
