Schematic of Transmission Oil Cooler (A) Coolant inlet port (B) Coolant outlet port (C) Oil outlet port (D) Oil inlet portCoolant from the engine comes in at inlet port (A). The coolant flows through many long tubes that are in the cooler. After the coolant goes through the tubes to the end cover, the coolant is returned back through different tubes. The coolant then goes out through outlet port (B). Coolant from outlet port (B) returns to the engine cylinder block.Power train oil with a high temperature comes from the torque converter outlet (D). This oil comes in at the side of the cooler. The oil flows around the tubes inside the cooler. In this process, heat is removed from the oil and transferred to the coolant of the engine. The coolant is then cooled by the engine cooling system.After the oil flows around the tubes in the cooler, the oil flows through passage (C). Oil from passage (C) then flows to the torque converter outlet relief valve.
