{"product_id":"thermal-bypass-and-flow-control-valve","title":"Thermal Bypass and Flow Control Valve","description":"The Superior Transmission Parts STL020 Sure~Cool® Thermal Bypass \/ Flow~Control valve is a USA-made upgrade for various automatic transmissions. This system ensures full-time cooler flow, providing immediate cooler fill and an accurate fluid level check without needing a warm-up cycle. It is recommended as preventive maintenance during transmission rebuilds or routine service.\n\nThis valve actively manages transmission fluid temperature by bypassing the cooler when cold and ensuring constant flow when warm. Features include a built-in safety bypass, reduced average operating temperatures, and increased ATF life. Compared to factory thermostatic pellet-style systems, the STL020 significantly reduces the risk of overheating and planetary gear damage.\n\nCompatible transmissions include the Ford 4R70, 4R75, 6F35, 6F50, 6F55, 6R80, and 6R90. It also works with late 2021-up GM 10L80 and 10L90 transmissions. Instructions are included with the part.","brand":"Superior Transmission Parts","offers":[{"title":"Default Title","offer_id":52866416017720,"sku":"STL020","price":30.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687704145.jpg?v=1787907498","url":"https:\/\/store.motormia.co\/products\/thermal-bypass-and-flow-control-valve","provider":"MOTORMIA","version":"1.0","type":"link"}
