{"product_id":"d4-atf-full-synthetic-automatic-transmission-fluid","title":"D4 ATF Full-Synthetic Automatic Transmission Fluid","description":"The Red Line D4 ATF is a high-performance, full-synthetic transmission fluid engineered to provide superior shear-stability and cold-weather operation compared to standard petroleum-based fluids. By maintaining stable frictional characteristics, it prevents the varnishing of valves and clutches that can lead to transmission failure over time, making it an excellent choice for both high- and low-mileage transmissions.\n\nIts formulation offers GL-4 gear protection, which is particularly effective for manual transmissions and transaxles like the T-5, T-45, and T-56 where proper synchronizer engagement is critical.\n\nImportant compatibility and usage notes: While this fluid is suitable for many manual and automatic applications, please note that Red Line MT-LV, MTL, MT-85, and MT-90 are not for use in differentials with hypoid gears. This fluid is fully compatible with petroleum-based oils and other synthetics, ensuring a smooth transition during fluid changes.","brand":"Red Line","offers":[{"title":"Default Title","offer_id":52689358389560,"sku":"D4ATF","price":18.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687612022.jpg?v=1784905660","url":"https:\/\/store.motormia.co\/products\/d4-atf-full-synthetic-automatic-transmission-fluid","provider":"MOTORMIA","version":"1.0","type":"link"}
