Koyo EC0013 Aluminum External Automatic Transmission Oil Cooler

The Koyo EC0013 Koyorad external automatic transmission oil cooler is designed to provide efficient cooling for your vehicle's automatic transmission fluid. This auxiliary cooler helps maintain optimal transmission temperatures, extending transmission life and improving performance under demanding conditions.

Key Features:

• Aluminum construction for excellent heat dissipation and corrosion resistance
• External mount design allows for flexible installation locations
• Enhances transmission cooling capacity beyond factory specifications
• Ideal for vehicles used in hot climates, towing, or performance applications
• High-quality Koyorad engineering ensures reliable long-term operation

This transmission oil cooler works by circulating hot transmission fluid through its aluminum core, where airflow dissipates heat before the fluid returns to the transmission. Installing an external cooler can significantly reduce transmission operating temperatures, helping prevent overheating-related damage and maintaining consistent shift quality.
