This is a primary cause for TCC-related slip code P1870 and overheated converters. Exhausting apply pressure also diminishes line pressure, which can result in burnt clutches. Excess wear at the isolator valve bore reduces TCC apply pressure.\u003c\/p\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cp\u003eReconditioning the bore and installing Sonnax TCC regulator and isolator valve kit 77754-04K restores normal TCC operation by reestablishing the hydraulic integrity of this circuit.\u003c\/p\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003eSleeve manufactured from highly wear-resistant aluminum\u003c\/li\u003e\n\n\u003cli\u003eHardcoat anodized aluminum regulator valve combats premature wear\u003c\/li\u003e\n\n\u003cli\u003eIsolator valve lengthened to operate in unworn portions of the bore\u003c\/li\u003e\n\n\u003cli\u003eAnnular grooves help center valves in bore to reduce future side-load wear\u003c\/li\u003e\n\n\u003c\/ul\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e","brand":"Suncoast Performance","offers":[{"title":"Default Title","offer_id":48219558314225,"sku":"SC-77754-04K","price":48.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/1344\/3057\/files\/Suncoast-TCC-Regulator-_-Isolator-Valve-Kit-Suncoast-Performance-151625159.jpg?v=1781626125","url":"https:\/\/tamelessperformance.com\/products\/suncoast-sc-77754-04k-tcc-regulator-isolator-valve-kit","provider":"TAMELESS PERFORMANCE","version":"1.0","type":"link"}
