Transmission Oil Cooler Kit 16 x 5-1/4 x 1-1/2

The Transmission Oil Cooler Kit 16 x 5-1/4 x 1-1/2 by NORTHERN RADIATOR is engineered for drivers who demand consistent transmission temperatures under sustained driving stress. Whether you're towing heavy loads, spirited track sessions, or daily commuting in high-heat environments, excessive transmission fluid temperature degrades viscosity and accelerates seal wear. This cooler kit intercepts hot fluid returning from your transmission before it enters the pan, dissipating thermal energy through aluminum core fins before recirculating clean, cool oil back into the system.

Northern Radiator's compact aluminum construction measures 16 x 5-1/4 x 1-1/2 inches, providing effective heat rejection in tight engine bays without excessive weight penalty at 4.5 lbs. The stacked-plate or tube-and-fin design maximizes surface area for efficient fluid-to-air heat transfer while maintaining low pressure drop across the core. Integrated inlet and outlet ports accommodate standard transmission cooler line fittings, and the complete kit includes all necessary hardware, brackets, and hose adapters for bolt-on installation. The aluminum core resists corrosion and vibration while delivering reliable performance across a broad temperature range typical of modern automatic and manual transmissions.

Transmission cooler kits benefit owners of heavy-duty trucks, performance cars, vehicles operating in desert or tropical climates, and anyone running higher-than-stock line pressure or modified torque converters. Installation typically requires routing auxiliary transmission cooler lines through the firewall or along the frame; front-mounted placement offers superior airflow exposure during city and highway driving. Verify fitment with your specific vehicle platform, as mounting brackets and line routing vary by make and model. This Northern Radiator cooler is a proven upgrade for extending transmission lifespan and maintaining optimal fluid condition during demanding applications.
