Transmission coolers will help your transmission's fluid stay within an optimal temperature range, to extend its life and performance. Excessive heat can damage your automatic transmission, seals, bearings, and burn fluid.  Our range of efficient coolers are available in a variety of dimensions for various applications. From thick to thin, compact to heavy duty, making it simple to install a remote trans cooler to help protect against costly transmission repairs. 

Options include 1} tube & fin 2) plate & fin 3) stack plate 4) heat sink. All our auxiliary transmission coolers are designed to keep fluid moving to ensure even cooling and prevent heat soak. For applications short on space or that require additional performance, the Derale range includes coolers with built-in electrical fans. Please check our listings as some units also include high-temperature/high-pressure hoses, mounting hardware, and fittings, whereas others may not.
