This reduced clutch pressure causes slippage and burn-up. The Sonnax drop-in replacement valve is slightly oversized and has extended spool lengths to provide additional sealing contact area. The stabilization flats on the inboard end of the spool maintain OE flow, but provide continual valve support while stroking. Annular grooves have been added to prevent side loading and a new spring is provided for the modified valve length. Sonnax Forward and Reverse abuse valve kit 77754-35K fits either the Forward or Reverse abuse location and includes a replacement bore plug.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eKit raises clutch pressure slightly to prevent slippage and burn-up, an advantage for heavy-duty, plowing or repetitive forward-reverse maneuvers\u003c\/li\u003e\n\u003cli\u003eEliminates leakage of clutch feed pressure to the exhaust port at the spring pocket\u003c\/li\u003e\n\u003cli\u003eOne valve and spring combination works for either Forward or Reverse abuse locations\u003c\/li\u003e\n\u003cli\u003eNo reaming is required for the slightly oversized drop-in replacement valve\u003c\/li\u003e\n\u003cli\u003eIncludes replacement abuse bore plug\u003c\/li\u003e\n\u003cli\u003eDrop-in Zip Valve™ parts install quickly and easily\u003c\/li\u003e\n\u003c\/ul\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\u003eValve\u003c\/li\u003e\n\u003cli\u003ePlug\u003c\/li\u003e\n\u003cli\u003eSpring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Sonnax","offers":[{"title":"Default Title","offer_id":48245743681758,"sku":"S74741UK","price":17.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/5464\/5470\/files\/S74741UK_1.jpg?v=1778782868","url":"https:\/\/transmissioncenter.net\/products\/4l60e-4l65-70e-forward-and-reverse-abuse-valve-heavy-duty-sonnax-77754-35k","provider":"Transmission Center","version":"1.0","type":"link"}
