The factory piston cracks or the lip seal hardens, causing loss of cushion pressure and slamming the 3rd clutch on every 2-3 shift — leading to burnt frictions and broken shafts. Installing this upgraded molded piston with permanently bonded rubber seal during your rebuild restores the factory-soft 2-3 upshift and dramatically extends 3rd clutch life.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003ePerfect fit for all 1991-Up models including:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul dir=\"auto\"\u003e\n \t\u003cli\u003eChevrolet\/GMC Silverado, Sierra, Suburban, Tahoe, Yukon\u003c\/li\u003e\n \t\u003cli\u003eCadillac Escalade, Hummer H1\u003c\/li\u003e\n \t\u003cli\u003eAll 4L80E \u0026amp; 4L85E applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eSymptoms of a failing piston:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul dir=\"auto\"\u003e\n \t\u003cli\u003eHard bang or clunk on 2-3 upshift\u003c\/li\u003e\n \t\u003cli\u003eDelayed then harsh 3rd gear engagement\u003c\/li\u003e\n \t\u003cli\u003eBurnt or glazed 3rd clutch frictions\u003c\/li\u003e\n \t\u003cli\u003eBroken intermediate sprag from shock load\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"auto\"\u003eDon’t let a $40 part destroy your $600 clutch pack — drop in the Stellar Automotive Group molded piston and shift smooth again.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e All parts are distributed, not designed or manufactured, by Stellar Automotive Group.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eAdd this must-have 4L80E upgrade to your cart today and feel the difference on every 2-3 shift!\u003c\/p\u003e","brand":"Trans Parts Direct","offers":[{"title":"Default Title","offer_id":52425242837173,"sku":"34108 P","price":31.6,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1006\/3872\/0181\/files\/34108-P-scaled.jpg?v=1786618709","url":"https:\/\/transpartsdirect.com\/products\/stellar-automotive-group-4l80e-piston-3rd-clutch-accum-fits-gm-91-up","provider":"Trans Parts Direct","version":"1.0","type":"link"}
