Circuit/System Description
The primary source of heat in the transmission is the torque converter. Hot oil exits the torque converter through the torque converter clutch (TCC)
control valve and flows to the transmission cooler supply line. The supply line connects to the cooler, which is in the radiator. From the cooler, the
oil returns through the oil cooler return line and enters the lubrication circuits. After lubricating the internal components, the oil returns to the oil
pan. The transmission fluid temperature sensor is located in the control solenoid valve assembly.
