Cooling system (1) Water pump (2) Radiator (3) Transmission oil cooler | |
Water pump (1) draws coolant from radiator (2) into transmission oil cooler (3). The coolant flows through the many long tubes that are in the oil cooler. The coolant then exits the opposite end of transmission oil cooler (3) and the coolant is pumped into the engine oil cooler. The coolant then circulates through the engine and back to radiator (2). Radiator (2) reduces the temperature of the coolant.

Schematic of a transmission oil cooler | |
Transmission system oil with a high temperature comes from the torque converter outlet. Transmission system oil enters the oil cooler inlet. The flow of oil is around the tubes and along the tubes inside the oil cooler. In this process, heat that is removed from the oil is given to the engine coolant. After the oil flows through the oil cooler tubes, the oil flows through the outlet of the transmission oil cooler with a lower temperature. The components in the transmission are then cooled and lubricated by the oil.
