12k Transmission Cooler

The DERALE 12K Transmission Cooler (Part #13101) is a compact aluminum and copper tube-type fluid cooler engineered to manage automatic transmission temperatures under sustained load. With 11/32-inch hose barb inlets and outlets, this cooler integrates easily into existing transmission cooling lines and is supplied with all necessary fittings and hardware for complete installation. The black powder-coated finish resists corrosion and UV degradation, making it suitable for both street and track applications where transmission fluid temperatures exceed factory cooling capacity.

At 8 x 2.1 x 18.6 inches and weighing just 2.45 pounds, this transmission cooler fits in tight engine compartments without requiring extensive modifications. The tube-type aluminum core design maximizes heat dissipation efficiency while minimizing weight—critical for street rods, drag vehicles, and high-performance street cars where transmission longevity depends on maintaining optimal fluid temperatures. The copper tubes enhance thermal conductivity, allowing rapid heat rejection even at highway speeds. All connection hardware and hose barbs are included, eliminating the need for additional sourcing.

This cooler is ideal for vehicles with automatic transmissions experiencing temperature creep during heavy towing, frequent acceleration, or sustained performance driving. Street rodders, muscle car enthusiasts, and transmission builders commonly specify transmission coolers like this to protect against delayed upshifts, harsh engagement, and premature fluid breakdown caused by excess heat. DERALE's 12K transmission cooler delivers effective thermal management for any build where OEM cooling is insufficient or aftermarket performance demands require independent temperature control.
