With the low boost problem results in complaints of soft 2-3, direct clutch failure as well as the gear ratio and solenoid performance codes. On the other hand, the runaway boost pressure problem results in costly broken case, direct drum and piston.\u003c\/p\u003e\n\u003ch5 style=\"text-align: left;\"\u003e\u003cstrong\u003eFeatures and benefits:\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cp style=\"text-align: left;\"\u003eThe TransGo 4L80E  SHIFT KIT® Valve Body Repair Kit includes valve body, case and pump components and modifications designed to deliver increased durability while providing short smooth shifts. These changes work in concert with a slight increase in line pressure to greatly improve the overall durability and shift feel of the transmission. The included highly improved wide land self-cleaning design boost valve and bushing resists wear so that pressure rise keeps working properly. Lastly, the EPC boost pressure relief valve system provided helps prevent runaway boost pressure to stop case and valve body wall blow-out due to excess pressure.\u003c\/p\u003e\n\u003ch5 style=\"text-align: left;\"\u003e\u003cstrong\u003eCorrects\/Prevents\/Reduces:\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cul style=\"text-align: left;\"\u003e\n\u003cli\u003eHigh pressure parts breakage\u003c\/li\u003e\n\u003cli\u003eSoft 2-3 shift\u003c\/li\u003e\n\u003cli\u003eBurnt direct clutch\u003c\/li\u003e\n\u003cli\u003eSlow 3-2 downshift\u003c\/li\u003e\n\u003cli\u003eNo upshifts\u003c\/li\u003e\n\u003cli\u003eHarsh 1-2 shift\u003c\/li\u003e\n\u003cli\u003eLow pressure due to solenoid filter breakup\u003c\/li\u003e\n\u003cli\u003eCodes 39, 68, 85, 86, 87, P0731, P0732, P0733, P0734, P0751, P0756, P0894 and P1870\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5 style=\"text-align: left;\"\u003e\u003cstrong\u003eIncludes:\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli style=\"text-align: left;\"\u003eUSA-made hardened boost valve and bushing\u003c\/li\u003e\n\u003cli style=\"text-align: left;\"\u003ePressure regulator valve spacer, washer, springs and snap ring\u003c\/li\u003e\n\u003cli style=\"text-align: left;\"\u003eNew stronger 4\u003csup\u003eth\u003c\/sup\u003e feed bolt and washer\u003c\/li\u003e\n\u003cli style=\"text-align: left;\"\u003e(2) Direct and reverse feed hole cup seals\u003c\/li\u003e\n\u003cli style=\"text-align: left;\"\u003eRelief valve system plate, valve, spring, e-clip and drill bit\u003c\/li\u003e\n\u003cli style=\"text-align: left;\"\u003e(2) Accumulator valve springs, end plug and O-ring\u003c\/li\u003e\n\u003cli style=\"text-align: left;\"\u003eActuator filter tapered plug, O-ring, spring and end plug\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"TransGo","offers":[{"title":"Default Title","offer_id":47966997283038,"sku":"T34165E","price":88.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/5464\/5470\/files\/T34165E_1.jpg?v=1773155298","url":"https:\/\/transmissioncenter.net\/products\/4l80e-4l85e-valve-body-repair-kit-transgo-sk-4l80e","provider":"Transmission Center","version":"1.0","type":"link"}
