Derale Performance Pass Series Transmission Cooler

The Derale Performance Pass Series Transmission Cooler is a tube and fin automatic transmission oil cooler. It helps keep fluid temperatures down in daily drivers, tow rigs, and performance builds. It can also be used as a power steering or fuel cooler. Lower fluid temperatures help protect the transmission from heat-related wear and failure.

Key Features:

• Tube and fin construction: Seamless copper tubing is expanded into aluminum cooling fins for efficient heat transfer.
• Turbulator inserts: Embossed turbulators inside the tubes agitate the fluid, which improves heat transfer.
• -6AN inlet and outlet fittings: The cooler has -6AN fittings for a secure connection to compatible lines.
• Multi-pass design: Each cooler has a multi-pass internal flow path to increase cooling surface area and dwell time.
• Protective finish: A black finish and plastic fin guards protect the core during handling and installation.
• Made in the USA by Derale, a long-established name in performance fluid cooling.

Pass count varies by part number, so pick the one that suits your cooling needs and available mounting space. These coolers are sold as cooler cores only, so plan to source hoses, mounting hardware, and any other installation parts separately. A cooler like this helps extend transmission and fluid life and supports consistent transmission performance.
