{"product_id":"low-pressure-drop-automatic-transmission-oil-cooler-1","title":"Low-Pressure Drop Automatic Transmission Oil Cooler","description":"The Tru-Cool LPD4454 (OC-4451) is a low-pressure drop automatic transmission oil cooler engineered by Long Manufacturing Ltd., a division of Dana Corporation. This cooler boasts a stacked plate design with 36 plates, offering a BTU rating of 13,000 and a Gross Vehicle Weight (GVW) rating of up to 18,000 lbs.\n\nThe cooler measures 7 1\/4\" x 11\" x 3\/4\" and utilizes 11\/32\" hose barb fittings. The product listing indicates that this unit is sold as a kit, which includes the oil cooler itself, hose, fittings, hardware, and two styles of mounting hardware utilizing quick-connect nylon straps and steel mounts. The manufacturer highlights that \"easy installation instructions\" are included and \"no special tools are required.\"\n\nTransmission oil plays a critical role in absorbing heat generated by the torque converter. This heated oil is pumped from the sump, passes through the torque converter and hydraulic control systems, and then exits to either an in-tank cooler (often located in the radiator) or a remote auxiliary cooler. The heat is transferred from the oil to the engine's cooling system or ambient air. For optimal performance, especially in demanding applications like towing or racing, auxiliary coolers like the Tru-Cool LPD4454 are essential to prevent overheating, maintain fluid integrity, and extend the life of the transmission components. The manufacturer claims Tru-Cool LPD coolers offer \"30% more cooling than tube-and-fin coolers\" and \"15 times less flow restriction.\"","brand":"Tru-Cool","offers":[{"title":"Default Title","offer_id":52689441718584,"sku":"LPD4454","price":111.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687740186.jpg?v=1784906635","url":"https:\/\/store.motormia.co\/products\/low-pressure-drop-automatic-transmission-oil-cooler-1","provider":"MOTORMIA","version":"1.0","type":"link"}
