It suits heavy duty Max 40K setups where sustained torque loads raise fluid temperatures quickly. This transmission oil cooler is a practical replacement for a clogged or leaking original unit on work vehicles that see constant use.\u003c\/p\u003e\u003ch4\u003eBuilt For Performance\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLow pressure design matched to the LPD47391 reference for consistent fluid flow\u003c\/li\u003e\n\u003cli\u003eCooling core built to handle sustained heavy duty transmission heat loads\u003c\/li\u003e\n\u003cli\u003eDesigned for Max Heavy Duty 40K applications where fluid temperature control matters\u003c\/li\u003e\n\u003cli\u003eDirect replacement footprint for simpler installation during service\u003c\/li\u003e\n\u003cli\u003eConstruction suited to constant duty cycles rather than light intermittent use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eOn-The-Job Use\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHeavy duty trucks running continuous haul or load cycles\u003c\/li\u003e\n\u003cli\u003eMax 40K drivetrain service and transmission fluid temperature management\u003c\/li\u003e\n\u003cli\u003eFleet maintenance where transmission overheating shortens fluid and clutch life\u003c\/li\u003e\n\u003cli\u003eReplacement of a failed or restricted original transmission cooler\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecs At A Glance\u003c\/h4\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number(s)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLPD47391\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAutomatic transmission oil cooler\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePressure Style\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLow pressure\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMax Heavy Duty 40K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch4\u003eGood To Know\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e What does a low pressure transmission oil cooler do? \u003cstrong\u003eA:\u003c\/strong\u003e It removes heat from automatic transmission fluid before the fluid returns to the gearbox, keeping operating temperatures in a safer range. A restricted or leaking cooler can lead to overheated fluid and rough shifting.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Should the cooler be matched to the transmission it serves? \u003cstrong\u003eA:\u003c\/strong\u003e Yes, flow rate and pressure rating should match the transmission it cools, which is why the LPD47391 reference matters here.
