Derale 13 Row Series 9500 Plate & Fin Transmission Cooler Kit – 13633

Protect your transmission and improve performance with the Derale 13 Row Series 9500 Plate & Fin Transmission Cooler Kit, part number 13633. Designed to meet the demands of light to medium duty vehicles, this cooler is a trusted solution for reducing transmission temperatures—especially during towing, hauling, or daily driving in hot conditions.

High-Efficiency Cooling with OEM-Trusted Technology

This transmission cooler features a durable furnace-brazed aluminum construction and an advanced plate and fin design with embossed turbulators to increase heat dissipation. These turbulators agitate fluid flow internally, ensuring maximum contact with the cooling surfaces while minimizing pressure drop. As a result, the 13-row cooler efficiently lowers fluid temperatures, helping your transmission run cooler, last longer, and perform better under load.

Why Add a Transmission Cooler?

Your transmission generates extreme heat, especially when towing, climbing hills, or driving in traffic. Excessive heat is the number one killer of automatic transmissions. A quality external transmission cooler like the Derale Series 9500 helps maintain safe operating temps, preventing slippage, fluid degradation, and premature wear. If you're planning an LS swap, performance build, or just want to protect your investment, this is one of the smartest upgrades you can make.
