Where does the oil exiting the torque converter typically go for cooling?

• A. Pump intake
• B. Transmission cooler
• C. Transmission sump
• D. Front lube circuit

Answer: (B)

When ATF leaves the torque converter it’s hot and needs cooling to keep the fluid and the transmission components from overheating. The fluid is routed through a transmission cooler—usually a radiator-style cooler in front of the radiator or a dedicated cooler—where it can shed heat to air. After it’s cooled, it returns to the transmission sump to be drawn back in by the oil pump and recirculated. This cooling loop helps protect clutches, gears, and seals and keeps the fluid viscosity within the right range.
