Koyo Aluminum Automatic Transmission Oil Cooler

The Koyo (Koyorad) Aluminum Automatic Transmission Oil Cooler line gives your transmission extra cooling. These external transmission coolers (also called auxiliary ATF coolers or trans coolers) lower automatic transmission fluid temperatures. Cooler fluid helps protect internal components from heat-related wear.

Key Features:

• Aluminum construction is lightweight and corrosion-resistant. It also transfers heat efficiently.
• External mounting design lets you install the cooler in a high-airflow location for better heat dissipation.
• Precision-engineered flow passages support efficient heat exchange with minimal pressure drop.
• Helps reduce fluid oxidation and breakdown. This can extend the life of the fluid and the transmission.
• Suited to demanding use such as towing, hauling, hot-weather driving and performance applications.

Koyo makes cooling products including radiators, oil coolers and intercoolers under the Koyorad name. Its manufacturing is ISO 9001 certified. Each cooler in this line is built to help keep transmission fluid temperatures in range and protect your drivetrain investment.
