{"product_id":"valve-body-repair-kit-7","title":"Valve Body Repair Kit","description":"The TransGo SK4L60E SHIFT KIT® is a valve body repair kit engineered to enhance the durability and performance of 1993-2015 General Motors vehicles equipped with the 4L60E, 4L65E, and 4L70E automatic transmissions. This kit is designed to correct and prevent common issues that plague these transmissions, including TCC slip or shudder, diagnostic trouble codes P1870 and P0894, harsh 1-2 shifts, double bump shifts, 2-3 flare-ups, burnt 3-4 clutch plates, and inconsistent pressure boost problems.\n\nThe kit addresses wear in the torque converter clutch regulator valve bore, a common cause of TCC slip complaints and related codes. It also rectifies inconsistent pressure boost and calibration issues within the shift accumulation system, which can lead to 3-4 clutch plate failure and 2-3 flare-ups. The SK4L60E includes components and modifications for the valve body, servo, pump, and accumulator, recalibrating the entire accumulation system with a slight increase in line pressure.\n\nKey features include USA-made hardened steel TCC isolator and regulator valves with longer lands to restore hydraulic integrity. The kit offers options for vehicles with or without active fuel management (AFM). The installation note indicates that transmission removal is not required, making it a more accessible repair. This kit is favored by professional transmission rebuilders for its ability to significantly improve the transmission's durability and shift feel, providing short, smooth shifts and a more efficient torque converter clutch apply.","brand":"TransGo","offers":[{"title":"Default Title","offer_id":52866457665848,"sku":"SK4L60E","price":47.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687748441.jpg?v=1787908256","url":"https:\/\/store.motormia.co\/products\/valve-body-repair-kit-7","provider":"MOTORMIA","version":"1.0","type":"link"}
