The Derale 15950 is an Atomic Cool remote transmission cooler kit for performance, muscle, hot rod, and truck applications, including heavy towing and hauling. It pairs a heavy-duty 15-row plate and fin cooler with an 8" reversible Tornado electric fan, so the cooler supplies its own airflow and can mount almost anywhere. A clear anodized aluminum shroud and brackets hold the assembly, and a 180°F in-line thermostat switches the fan on by fluid temperature. The kit includes everything needed to install on vehicles with 1/2" transmission cooler lines.
