{"product_id":"sonnax-boost-valve-assembly","title":"Sonnax Boost Valve Assembly","description":"The ZZPerformance Sonnax Boost Valve Assembly (84754-30K) is engineered to resolve common performance and hydraulic issues in GM 4T65-E transmissions, including soft or delayed upshifts, particularly between 1st and 2nd gears, and delayed reverse engagement. These symptoms are often attributed to wear in the original equipment (OE) boost sleeve assembly, which consists of steel valves and a plug that wear down the aluminum sleeve, leading to crucial boost pressure leaks.\n\nUnlike the OE assembly, which is not serviceable separately and necessitates replacing the entire valve body, the Sonnax Boost Valve Assembly offers an upgraded solution. It allows for the salvage of the original valve body by directly replacing the worn components, thereby restoring the transmission's hydraulic integrity. The kit includes a valve and sleeve constructed from hard-anodized aluminum, chosen for its superior wear resistance. The valve design promotes increased oil lubricity, ensures proper valve centering, and contributes to overall longevity.\n\nThe accompanying sleeve is crafted from highly wear-resistant aluminum and features integrated oil channels. These channels are crucial for ensuring the uniform distribution of boost valve oil throughout the assembly, optimizing lubrication and cooling. This design ensures consistent performance and extends the lifespan of the transmission components. The entire kit is designed as a direct, drop-in replacement, meaning it requires no specialized machining or complex modifications to the existing valve body, simplifying the installation process for technicians and enthusiasts alike.","brand":"ZZPerformance","offers":[{"title":"Default Title","offer_id":52871896596792,"sku":"84754-30K","price":78.88,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/sonnax-boost-valve-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
