The factory piston commonly cracks or loses its bond under heat and mileage, causing internal leakage that weakens intermediate apply — leading to flare on upshifts, slipping under load, and rapid clutch failure. This molded piston with permanently bonded rubber seal restores full line pressure, delivers crisp 2nd-to-3rd transitions, and protects your intermediate clutch pack for reliable daily driving or light towing.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003ePerfect fit for popular models including:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul dir=\"auto\"\u003e\n \t\u003cli\u003eChevrolet Trailblazer, SSR\u003c\/li\u003e\n \t\u003cli\u003eBMW 3 Series (E46), 5 Series (E39)\u003c\/li\u003e\n \t\u003cli\u003eCadillac CTS (early), Escalade (select)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eSymptoms of a failing intermediate clutch piston:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul dir=\"auto\"\u003e\n \t\u003cli\u003eFlare or slip on 2-3 upshift\u003c\/li\u003e\n \t\u003cli\u003eDelayed engagement in intermediate gear\u003c\/li\u003e\n \t\u003cli\u003eHarsh shifts when clutches finally grab\u003c\/li\u003e\n \t\u003cli\u003eBurnt intermediate frictions on teardown\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"auto\"\u003eDon’t let a $50 piston destroy a $500 clutch pack — install the Stellar Automotive Group molded intermediate piston and shift strong through every gear.\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 essential 4L40E\/5L40E rebuild part to your cart today and enjoy crisp, reliable shifts!\u003c\/p\u003e","brand":"Trans Parts Direct","offers":[{"title":"Default Title","offer_id":52425244410037,"sku":"55767 PAFT","price":30.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1006\/3872\/0181\/files\/55767-PAFT-scaled.jpg?v=1786618935","url":"https:\/\/transpartsdirect.com\/products\/stellar-automotive-group-4l40e-5l40e-intermediate-clutch-molded-piston-fits-gm","provider":"Trans Parts Direct","version":"1.0","type":"link"}
