Heat is what wears a transmission out. The Mishimoto Transmission Cooler attacks the problem with raw capacity: a tube-and-fin core with a 245% increase in core volume over stock, giving the system far more headroom to keep fluid temperatures in a safe range when the truck is working hardest.----The core also adds a 137% increase in frontal area, putting more of the cooler directly in the incoming airstream, and a 173% increase in external fin area to move heat from the fluid into the air more efficiently. All-aluminum construction handles the thermal demands of stock and modified Duramax trucks alike, and the cooler retains the factory transmission line connections for a clean, complete upgrade with no additional adapters or plumbing.----Direct fit for the 2020+ Chevrolet and GMC Duramax L5P 6.6L. No drilling, cutting, or modification required. Backed by the Mishimoto Lifetime Warranty.\u003c\/p\u003e\n\u003ch4\u003eFeatures \u0026amp; Benefits\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e245% larger core volume for serious heat dissipation - the oversized tube-and-fin core gives the transmission far more capacity to pull heat from the fluid under tow and heavy load.\u003c\/li\u003e\n\u003cli\u003eTube-and-fin aluminum core built for sustained load - durable all-aluminum construction holds transmission temps in check through the heat of towing where stock cooling falls short.\u003c\/li\u003e\n\u003cli\u003e173% more external fin area accelerates heat transfer - the added fin surface moves thermal energy from the fluid into the airstream far more efficiently than the stock cooler.\u003c\/li\u003e\n\u003cli\u003eFactory connections, no adapters required - the cooler uses the OEM transmission line connections for a complete bolt-on upgrade with no extra fittings or plumbing work.\u003c\/li\u003e\n\u003cli\u003e137% more frontal area catches more cooling airflow - the larger frontal core area puts more of the cooler in the incoming airstream to drop fluid temps faster.\u003c\/li\u003e\n\u003cli\u003eDrops in without modification - confirmed direct fit for 2020+ Chevrolet and GMC Duramax L5P 6.6L trucks, with no cutting, fabricating, or adapter work required\u003c\/li\u003e\n\u003cli\u003eOwn it for life - backed by Mishimoto’s Lifetime Warranty, your investment is protected long after install day.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Mishimoto","offers":[{"title":"Default Title","offer_id":46295522312328,"sku":"misMMTC-DMAX-20","price":336.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/2491\/6104\/files\/dc2b2eb57ecc3b8a4a5bfc080ea2d9f8_1caa4e25-3164-4bb6-bc9f-129c912406c0.jpg?v=1786089762","url":"https:\/\/www.allianceracing.com\/products\/mishimoto-2020-chevrolet-gmc-duramax-l5p-6-6l-transmission-cooler-mmtc-dmax-20","provider":"Alliance Racing","version":"1.0","type":"link"}
