These problems can occur due to sleeve wear allowing torque signal and\/or accumulator pressure leakage, sticking valves or using the incorrect accumulator valve ratio for the application.\u003c\/p\u003e\n\n\u003cp\u003eThe 4L60-E series valve train has three OE size variations; CX, DX, and YZ. The size variations are clearly stamped with the letters on the aluminum sleeve. The most commonly found size is the DX. However, these versions are not available unless scavenged from other valve bodies. Sonnax accumulator valve train kit 77754-10K is specifically designed for the DX size with additional selective springs to cover the CX and YZ sizes.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eSleeve is manufactured from high-quality aluminum designed to prevent excessive wear due to the reciprocating motion of the steel valve\u003c\/li\u003e\n\u003cli\u003eContains three selective springs\u003c\/li\u003e\n\u003cli\u003eDrop-in Zip Valve™ parts install quickly and easily\u003c\/li\u003e\n\u003c\/ul\u003e\n\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\u003eSleeve\u003c\/li\u003e\n\u003cli\u003eSprings (3) \u003cem\u003eSelective\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003ePlug\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\u003e1-2 Bang at light throttle\u003c\/li\u003e\n\u003cli\u003eReduced 2-4 band life\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\nAvailable accumulator valve train kit ratios in GM 200-R4 and 4L60 units do not support the 4L60-E family of transmissions, impacting shift feel and resulting in poor shift quality.\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\nSonnax drop-in accumulator valve train kit, designed for later model applications, will eliminate oil loss and maintain holding power to ensure proper shift feel.\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\/184198.pdf?v=1793635219\" 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":49129566601435,"sku":"77754-10K","price":144.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/4173\/0267\/files\/F198655871.jpg?v=1786547054","url":"https:\/\/suncoastperformance.com\/products\/accumulator-valve-train-kit-stamp-codes-cx-dx-or-yz-only","provider":"SunCoast Diesel","version":"1.0","type":"link"}
