Excessive heat is one of the biggest transmission killers on trucks that tow, haul, or put power down, and the factory cooler is barely adequate for stock applications. The Fluidyne stacked plate cooler offers three times the core area and three times the fluid capacity of a traditional tube-and-fin cooler for superior heat dissipation and stable temperatures under heavy loads.\u003c\/p\u003e\n\u003cp\u003eFluidyne deliberately leaves out a thermostat, since thermostats can stick closed and cut off fluid circulation, so the cooler delivers unrestricted, consistent cooling. Fluidyne cooling systems are trusted in NASCAR and high-performance applications and are built to withstand extreme conditions. This cooler requires a Fluidyne line kit, sold separately: TLK.68.0709 for 68RFE trucks, TLK.48.0307 (keeps the OEM heat exchanger) or TLK.48.0307NH (bypasses it) for 48RE trucks.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eStacked plate design with three times the core area of tube-and-fin\u003c\/li\u003e\n\u003cli\u003eThree times the fluid capacity of a standard cooler\u003c\/li\u003e\n\u003cli\u003eNo thermostat to stick closed and starve the cooler\u003c\/li\u003e\n\u003cli\u003eBuilt from high-quality materials and tested in demanding conditions\u003c\/li\u003e\n\u003cli\u003eRace-proven Fluidyne cooling technology used in NASCAR\u003c\/li\u003e\n\u003cli\u003eLowers transmission temperatures under tow and heavy load\u003c\/li\u003e\n\u003cli\u003eInstalls with minimal modifications\u003c\/li\u003e\n\u003cli\u003eDesigned for the 48RE and 68RFE transmissions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Fluidyne\u003c\/li\u003e\n\u003cli\u003ePart Number: RT-48-0309\u003c\/li\u003e\n\u003cli\u003eType: Transmission Cooler\u003c\/li\u003e\n\u003cli\u003eCore Design: Stacked Plate\u003c\/li\u003e\n\u003cli\u003eMaterial: Aluminum\u003c\/li\u003e\n\u003cli\u003eThermostat: None\u003c\/li\u003e\n\u003cli\u003eTransmission: 48RE, 68RFE\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eIncluded:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e(1) Fluidyne Upgraded Stacked Plate Transmission Cooler\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e2003-2009 Dodge Ram 2500 5.9L\/6.7L Cummins Diesel (48RE, 68RFE)\u003c\/li\u003e\n\u003cli\u003e2003-2009 Dodge Ram 3500 5.9L\/6.7L Cummins Diesel (48RE, 68RFE)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLine kit required, sold separately: TLK.68.0709 (68RFE), TLK.48.0307 or TLK.48.0307NH (48RE)\u003c\/li\u003e\n\u003cli\u003eCooler does not include a thermostat\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Fluidyne","offers":[{"title":"Default Title","offer_id":48894993432733,"sku":"RT-48-0309","price":499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/2504\/1821\/files\/RT-48-0309.webp?v=1789051625","url":"https:\/\/rudysdiesel.com\/products\/fluidyne-upgraded-transmission-cooler-for-2003-2009-dodge-ram-2500-3500-cummins-48re-68rfe","provider":"Rudy's Performance Parts","version":"1.0","type":"link"}
