{"product_id":"oversized-low-overrun-valve-kit","title":"Oversized Low Overrun Valve Kit","description":"\n\u003cdiv class=\"spaced-vertical\"\u003e\n\u003cp\u003eThe low overrun valve directs line pressure to the reverse input and low and reverse clutches. As the bore deteriorates, line pressure at the inboard location cross-leaks into the low\/overrun circuit and to exhaust. Line pressure can also cross-leak to exhaust at the outer spool location, in both cases the loss of line pressure reduces clutch apply pressure in Reverse and Manual 1st, resulting in burnt clutches. As the bore wear becomes significant, the low overrun valve can become stuck in the bore resulting in loss of Reverse or Manual 1st Gears.\u003c\/p\u003e\n\n\u003cp\u003eReconditioning the bore and installing Sonnax oversized low overrun valve kit 77754-62K restores hydraulic integrity of the circuit and salvages worn valve bodies in GM 4L60-E, 4L65-E, 4L70-E transmissions.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eHardcoat anodized aluminum valve combats premature wear\u003c\/li\u003e\n\u003cli\u003eNew spring provided for proper calibration\u003c\/li\u003e\n\u003cli\u003eIncludes oversized bore plug\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\u003ePlug\u003c\/li\u003e\n\u003cli\u003eValve\u003c\/li\u003e\n\u003cli\u003eSpring\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-30503150-reamer-f-tool-kit-for-77754-62k.html\"\u003eF-77754-TL62\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\u003eBurnt Reverse clutch\u003c\/li\u003e\n\u003cli\u003eBurnt Low\/Reverse clutch\u003c\/li\u003e\n\u003cli\u003eNo Reverse\u003c\/li\u003e\n\u003cli\u003eNo Manual 1st\u003c\/li\u003e\n\u003cli\u003eSlips in Forward \u0026amp; Reverse\u003c\/li\u003e\n\u003cli\u003eLow line pressure in Reverse\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\nWear in the bore of the low overrun valve can lead to critical oil loss and reduced apply pressure at the reverse input and low and reverse clutches.\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\nRecondition the bore and install Sonnax oversized low overrun valve kit to restore valuable clutch apply pressure.\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\/184220.pdf?v=1793635250\" 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":49129567092955,"sku":"77754-62K","price":55.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/4173\/0267\/files\/F198655927.jpg?v=1786547071","url":"https:\/\/suncoastperformance.com\/products\/oversized-low-overrun-valve-kit","provider":"SunCoast Diesel","version":"1.0","type":"link"}
