{"product_id":"oversized-pressure-regulator-valve-kit","title":"Oversized Pressure Regulator Valve Kit","description":"\n\u003cdiv class=\"spaced-vertical\"\u003e\n\u003cp\u003eVehicles equipped with Chrysler 45RFE, 545RFE, 65RFE, 66RFE and 68RFE transmissions can develop erratic or high line pressure due to excessive wear in the OE pressure regulator valve bore. This wear allows critical oil loss, preventing correct line pressure regulation. Without adequate balance oil pressure, the PR valve will be out of its desired position, resulting in line pressure instability and possibly restricting cooler and lube flow. A deteriorated bore can cause lowered line pressure, resulting in soft shifting and burnt clutches. Reconditioning the bore and installing Sonnax oversized pressure regulator valve kit 44912-10K restores pressure regulator action for line pressure control in all ranges.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eHardcoat anodized aluminum valve combats premature wear\u003c\/li\u003e\n\u003cli\u003eAnnular grooves help center valve in bore to reduce side-load wear\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c\/div\u003e\n\u003cdiv class=\"part-accordion cb spaced-vertical\"\u003e\n\u003cp\u003e\u003cstrong\u003e\u003clabel for=\"components-panel\"\u003eContents:\u003c\/label\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"accordion-content\"\u003e\n\u003cul\u003e\n\u003cli\u003eValve\u003c\/li\u003e\n\u003cli\u003eGreen Spring \u003cem\u003eOE Pressure\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003eYellow Spring \u003cem\u003eUse with \u003ca href=\"..\/i-30502995-line-pressure-booster-kit.html\"\u003eRFE-LB1\u003c\/a\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eRequired Parts:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eReamer F-Tool Kit - Part No. \u003ca href=\"..\/i-30503035-reamer-f-tool-kit-for-44912-10k-44912-15k.html\"\u003eF-44912-TL10\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"col-4\"\u003e\n\u003cp\u003e\u003cstrong\u003eSymptoms:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHarsh shifts\u003c\/li\u003e\n\u003cli\u003eErratic line pressure\u003c\/li\u003e\n\u003cli\u003eBroken parts due to excessive line pressure\u003c\/li\u003e\n\u003cli\u003eHigh line pressure\u003c\/li\u003e\n\u003cli\u003eBurnt clutches\u003c\/li\u003e\n\u003cli\u003eRestricted converter\/lube flow\u003c\/li\u003e\n\u003cli\u003eSoft shifts\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c\/div\u003e\n\u003cdiv class=\"col-4\"\u003e\n\u003cp\u003e\u003cstrong\u003eCause:\u003c\/strong\u003e\u003c\/p\u003e\nExcess pressure regulator bore wear allows fluid loss, preventing normal line pressure control.\u003c\/div\u003e\n\u003cdiv class=\"col-4\"\u003e \u003c\/div\u003e\n\u003cdiv class=\"col-4 last\"\u003e\n\u003cp\u003e\u003cstrong\u003eCorrection:\u003c\/strong\u003e\u003c\/p\u003e\nRestore appropriate line pressure in all ranges by reconditioning the bore and installing wear-resistant Sonnax oversized pressure regulator valve kit.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e \u003c!-- suncoast-documents:start --\u003e\u003cdiv class=\"suncoast-product-documents\"\u003e\n\u003ch3 class=\"h6\"\u003eDocuments\u003c\/h3\u003e\n\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0832\/4173\/0267\/files\/184300.pdf?v=1793635066\" target=\"_blank\" rel=\"noopener\"\u003eInstructions\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/div\u003e\u003c!-- suncoast-documents:end --\u003e","brand":"Sonnax","offers":[{"title":"Default Title","offer_id":49129560539355,"sku":"44912-10K","price":82.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/4173\/0267\/files\/F198655505.jpg?v=1786546885","url":"https:\/\/suncoastperformance.com\/products\/oversized-pressure-regulator-valve-kit","provider":"SunCoast Diesel","version":"1.0","type":"link"}
