As a result, the transmission may have the incorrect diameter boost valves for the given application. Consequently, if the wrong diameter boost valve is installed, shifts will be soft or flared and the unit will experience repeated friction element failure due to inadequate line pressure.\u003c\/p\u003e\n\u003cdiv class=\"col col-sm-6  col-xs-12\"\u003e\n\u003ch4\u003eWhat is a boost valve ?\u003c\/h4\u003e\n\u003cp\u003eThe TV boost valve influences line pressure in accordance to the throttle valve pressure cable stroke. The low-int\/reverse boost valve provides a static pressure increase as well as determining the fixed line pressure value in manual 2\u003csup\u003end\u003c\/sup\u003e and 1\u003csup\u003est\u003c\/sup\u003e ranges. Adequate main line pressure is required to provide enough clamping force under all load conditions to prevent slipping, as well as to achieve proper shift quality. Consequently, incorrect diameter boost valves will cause complaints of soft shifts, flare shifts and burnt friction elements.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eFeatures and benefits:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThese TransGo replacement boost valve and bushing assemblies provides you with an economical and durable direct replacement for the OEM assembly.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eCorrects\/Prevents\/Reduces:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eInsufficient line rise\u003c\/li\u003e\n\u003cli\u003eSoft, slipping or flaring shifts\u003c\/li\u003e\n\u003cli\u003eBurned friction material\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"rt_comments rt_form\" id=\"comments\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"TransGo","offers":[{"title":"Default Title","offer_id":48124631056606,"sku":"A74507RBK","price":22.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/5464\/5470\/files\/A74507RBK_1.jpg?v=1776441996","url":"https:\/\/transmissioncenter.net\/products\/200-4r-700r4-4l60-pump-pressure-boost-valve-kit-500-transgo-7-500","provider":"Transmission Center","version":"1.0","type":"link"}
