Built for high-horsepower applications, heavy towing, and aggressive tuning, this complete valve body replaces the factory unit with a precision-engineered assembly designed to eliminate common hydraulic failures and withstand elevated line pressures.\u003c\/p\u003e\n\u003cp\u003eAt the heart of this upgrade is Tier One's CNC-machined 6061 billet aluminum channel plate. Nearly three times thicker than the factory casting and machined to an ultra-flat .0003-inch tolerance, the billet plate virtually eliminates channel plate flex that causes gasket failures, internal cross-leaks, and hydraulic pressure loss. The result is improved clutch apply pressure, more consistent shifting, and exceptional durability under demanding conditions.\u003c\/p\u003e\n\u003cp\u003eThis valve body also addresses every major weak point in the factory hydraulic system. Billet three-ring accumulator pistons replace the failure-prone factory plastic pistons, while an upgraded steel solenoid switch valve helps eliminate bore wear that commonly triggers P0871 diagnostic codes and Overdrive clutch failure. A bonded separator plate further improves hydraulic sealing and fluid control for maximum transmission reliability.\u003c\/p\u003e\n\u003cp\u003eEvery valve body is assembled using new critical components and tested on Tier One's in-house valve body dyno to verify proper operation before shipment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eComplete 68RFE valve body assembly\u003c\/li\u003e\n\u003cli\u003eCNC-machined 6061 billet aluminum channel plate\u003c\/li\u003e\n\u003cli\u003eNearly three times thicker than the factory channel plate\u003c\/li\u003e\n\u003cli\u003eMachined to .0003-inch flatness for superior sealing\u003c\/li\u003e\n\u003cli\u003eDesigned to withstand high horsepower and elevated line pressure\u003c\/li\u003e\n\u003cli\u003eIncludes bonded separator plate\u003c\/li\u003e\n\u003cli\u003eBillet three-ring accumulator pistons\u003c\/li\u003e\n\u003cli\u003eNew steel solenoid switch valve\u003c\/li\u003e\n\u003cli\u003eNew OEM transmission solenoid\u003c\/li\u003e\n\u003cli\u003eHelps eliminate P0871 diagnostic trouble codes\u003c\/li\u003e\n\u003cli\u003eReduces channel plate flex, gasket failure, and internal cross-leaks\u003c\/li\u003e\n\u003cli\u003eImproves hydraulic pressure control and transmission durability\u003c\/li\u003e\n\u003cli\u003eDyno tested prior to shipment\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tier One Transmissions","offers":[{"title":"Default Title","offer_id":52587155325211,"sku":"TODT1-68-AVBB-19","price":1799.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0962\/5757\/3147\/files\/68rfe_19plus_underside.webp?v=1784065764","url":"https:\/\/wwmperformance.com\/products\/tier-one-transmissions-68rfe-billet-high-pressure-valve-body-todt1-68-avbb-19-2019-2024-6-7l-cummins","provider":"WWM Performance","version":"1.0","type":"link"}
