This upgraded 15-row cooler replaces earlier 13-row designs to improve heat rejection while minimizing flow restriction, and it’s built from brazed aluminum for strength and corrosion resistance.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this cooler reduce transmission temperatures?\u003c\/h3\u003e\n\u003cp\u003eThe larger core area and additional rows increase the surface for heat exchange, so hot ATF dissipates faster into passing air. KOROP’s brazed-aluminum construction conducts heat efficiently and resists leaks under pressure, delivering more consistent operating temperatures during towing or stop-and-go driving.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e15 heat-exchange rows for increased cooling capacity\u003c\/li\u003e\n  \u003cli\u003eBrazed aluminum core for better thermal conduction and durability\u003c\/li\u003e\n  \u003cli\u003eLow-pressure-drop design to maintain flow while cooling\u003c\/li\u003e\n  \u003cli\u003eImproved energy-efficiency ratio compared with smaller cores\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill it fit my vehicle and replace my old cooler?\u003c\/h3\u003e\n\u003cp\u003eThe LPD47391 is engineered as a direct replacement for common 40K transmission coolers and lists compatibility with many cars, vans, light trucks, RVs, and towing setups.
