Schematic for the power train oil cooler (A) Coolant inlet (B) Coolant outlet (C) Oil outlet (D) Oil inletThe engine coolant enters the oil cooler at inlet (A) . Coolant flows through the tubes in the cooler. The coolant removes heat from the oil. The coolant then flows out of the oil cooler through outlet passage (B) . The coolant is then cooled by the engine cooling system.High temperature power train oil enters the cooler from the torque converter outlet relief valve. This oil enters the oil cooler at inlet (D) . The oil flows along the tubes in the oil cooler.The heat is removed from the oil and the heat is transferred to the engine coolant. The coolant temperature is cooled by the engine cooling system. The power train oil exits through passage (C) . The oil now has a cooler temperature.The cooled oil then flows to the priority valve. The priority valve divides the flow between the transmission and the steering and clutches for lubrication and for cooling.
