Plate & Fin Trans Cooler Kit

The Plate & Fin Trans Cooler Kit by DERALE is an essential upgrade for any vehicle owner serious about transmission longevity and performance reliability. Whether you're towing heavy loads, driving in extreme heat, or pushing your engine in spirited driving conditions, transmission fluid temperatures climb rapidly without adequate cooling capacity. This kit directly addresses thermal stress by adding dedicated cooling surface area, preventing the sluggish shifts, fluid degradation, and premature wear that accompany elevated trans temps. Mechanics and enthusiasts recognize that transmission cooling is one of the most cost-effective investments in drivetrain protection.

DERALE's plate and fin design maximizes heat dissipation through aluminum construction and efficient fin geometry that increases surface area for fluid-to-air heat exchange. The compact footprint (9.8 x 2.7 x 26.95 inches) allows straightforward installation in tight engine bay spaces without major modifications to existing cooling circuits. Weighing just 6.01 lbs, the cooler integrates seamlessly into OEM transmission cooling lines, using standard AN fittings and hose connections that any competent DIY mechanic or professional shop can handle. The plate and fin architecture resists clogging better than tube-and-strip designs and provides superior durability under vibration and thermal cycling common in automotive duty.

This cooler kit benefits trucks, SUVs, performance cars, and any modified vehicle where factory transmission thermal management falls short of real-world demands. It's particularly valuable for owners upgrading to larger tires, higher boost levels, or increased towing capacity—changes that inherently generate additional heat. Installation typically requires basic hand tools and a working knowledge of your vehicle's cooling circuit routing; consult your manufacturer's service manual or seek professional installation if unsure. The DERALE Plate & Fin Trans Cooler Kit (SKU DER13633) delivers measurable temperature drops that extend fluid life, improve shift quality, and provide peace of mind during aggressive driving or hauling. For serious automotive enthusiasts and mechanics, this cooler represents insurance against one of the most common causes of transmission failure.
