Derale Performance 12902 Series 6000 Transmission Cooler 15 Inch 4-Pass Aluminum

The Derale Performance 12902 Series 6000 Dyno-Cool transmission cooler is engineered to prevent heat-related transmission failures and extend the life of your vehicle's transmission. This high-performance aluminum cooler improves transmission performance by maintaining optimal fluid temperatures during demanding driving conditions.

Key Features:

• 15-inch length 4-pass cooler design for maximum heat dissipation
• Embossed turbulators inserted in each tube agitate fluid for superior heat transfer
• 1/2-inch aluminum tubing expanded into aluminum fins for durability and efficiency
• All-aluminum construction resists corrosion and provides excellent thermal conductivity
• Compact design fits a wide range of applications

This transmission cooler works by passing transmission fluid through multiple aluminum tubes with internal turbulators that create turbulence in the fluid flow. This turbulent action dramatically increases the surface contact between the hot fluid and the cooler aluminum tubes, resulting in more efficient heat transfer. The 4-pass design ensures fluid makes multiple passes through the cooling core before returning to the transmission, maximizing heat removal. Ideal for towing, performance driving, or any application where transmission temperatures need to be controlled.
