Hayden Automotive 777 Rapid-Cool 37mm Heavy Duty Engine/Transmission Cooler

Hayden's 37 millimeter heavy duty plate and fin coolers are ideal for transmission and engine oil cooling applications requiring higher flow range and increased heat transfer in a compact space. Over 14 million transmissions fail every year, 9 out of 10 from overheating. Every 20 degree drop in operating temperature can double oil and equipment life.
