The do88 OC-210 replaces the factory transmission cooler with a dual-pass unit that has 71 percent more core volume and 50 percent more cooling surface, while keeping oil pressure close to stock.\u003c\/p\u003e\n\u003cp\u003eIt uses harmonica-style tubes with internal channels to put more of the fluid in contact with the cooling surface, and the dual-pass layout holds the oil in the cooler longer to shed more heat. It keeps the OE-style quick-connect fittings and drops into the factory location with no modifications. Capacity rises from about 6 dl to 8.5 dl, so the fluid level needs to be checked after installation.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCore volume 71 percent larger; cooling surface 50 percent larger than OE\u003c\/li\u003e\n\u003cli\u003eDual-pass design with internally channeled harmonica tubes\u003c\/li\u003e\n\u003cli\u003eOil capacity 8.5 dl (OE 6 dl), about 42 percent more\u003c\/li\u003e\n\u003cli\u003eOil pressure kept close to OE levels\u003c\/li\u003e\n\u003cli\u003eOEM-style quick-connect inlet and outlet\u003c\/li\u003e\n\u003cli\u003eDrop-in fit for the ZF 8HP automatic\u003c\/li\u003e\n\u003cli\u003eReplaces OE 17118095284\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003edo88 performance transmission cooler\u003c\/li\u003e\n\u003cli\u003eRock guard\u003c\/li\u003e\n\u003cli\u003eFoam strip, 2 × zip-ties and 2 × 12 mm silicone caps\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequired extras:\u003c\/strong\u003e ZF 8HP transmission fluid to the manufacturer specification to top up after installation (the cooler holds about 2.5 dl more than stock), plus a drain tray.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation instructions (do88):\u003c\/strong\u003e \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2307\/8117\/files\/do88-OC-210-installation-instructions.pdf?v=1794357883\"\u003eOC-210 S58 transmission cooler installation instructions (PDF)\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003edo88 video (S58 parts overview):\u003c\/strong\u003e \u003ca href=\"https:\/\/www.youtube.com\/watch?v=IOVmUE4TnZE\u0026amp;t=410s\"\u003edo88 BMW G8X S58 upgrades – transmission cooler section (YouTube)\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation notes:\u003c\/strong\u003e remove the front wheels, wheel liners and front bumper, then the grille frame, radiator bracket, auxiliary radiator, brake ducts and bumper bar.
