Transmission Oil Cooler.
Coolant from engine enters one end of oil cooler and flows through many long oil cooler tubes. Coolant
then exits opposite end of oil cooler and returns to engine cylinder block. Coolant is then cooled by engine
Transmission system oil with a high temperature comes from torque converter outlet relief valve, then
enters oil cooler inlet. Flow of oil is around and along tubes inside oil cooler. As oil flows through tubes,
heat is removed from oil and given to engine coolant. After oil flows through oil cooler tubes it flows
through bottom outlet with a lower temperature. Components in transmission are then cooled and lubri-
cated by this oil.
