The factory piston commonly cracks or loses its bond under heat and torque, causing internal leakage that weakens low\/reverse apply — leading to no reverse, slipping in 1st gear, and rapid clutch failure. This upgraded molded piston with permanently bonded rubber seal restores full line pressure, delivers instant, firm reverse engagement and solid 1st gear hold, and protects your low\/reverse clutch pack even under heavy towing or performance use.\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 Silverado, Tahoe, Camaro\u003c\/li\u003e\n \t\u003cli\u003eGMC Sierra, Yukon\u003c\/li\u003e\n \t\u003cli\u003eCadillac Escalade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eSymptoms of a failing low\/reverse piston:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul dir=\"auto\"\u003e\n \t\u003cli\u003eNo or delayed reverse engagement\u003c\/li\u003e\n \t\u003cli\u003eSlipping or flare in 1st gear\u003c\/li\u003e\n \t\u003cli\u003eHarsh clunk when reverse grabs\u003c\/li\u003e\n \t\u003cli\u003eBurnt low\/reverse frictions on teardown\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"auto\"\u003eDon’t let a $50 piston destroy a $600 clutch pack — install the bonded low\/reverse piston and get reverse \u0026amp; 1st gear back to factory strength.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eAdd this essential 6L80\/6L90 rebuild part to your cart today and restore confident shifting!\u003c\/p\u003e","brand":"Trans Parts Direct","offers":[{"title":"Default Title","offer_id":52425115467957,"sku":"135765B UP","price":86.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1006\/3872\/0181\/files\/New-AC-DELCO-6L806L90-LowRev-Clutch-Piston-12-Notch-24224172-302577581518.jpg?v=1786609082","url":"https:\/\/transpartsdirect.com\/products\/6l80-6l90-low-reverse-bonded-piston-fits-gm","provider":"Trans Parts Direct","version":"1.0","type":"link"}
