{"product_id":"category-3-transmission-assembly","title":"Category 3 Transmission Assembly","description":"The Suncoast Performance SC-10L1000 Category 3 Transmission with Pro-Loc Valve Body and Deep Pan is engineered to be a substantial upgrade over factory 10L1000 transmissions, particularly for heavy-duty applications. This unit focuses on enhancing durability, torque handling, and overall reliability to withstand demanding conditions such as heavy hauling, towing, and off-road use. The design improvements aim to minimize breakdowns and reduce vehicle downtime, contributing to increased productivity and potentially lower maintenance expenses.\n\nKey components included in this transmission assembly are Raybestos Powertrain GPZ Frictions and Steels, a 10L1000 Transmission Overhaul Kit, a Pan Filter, and a 10L1000 Deep Cast Aluminum Pan offering 4 quarts of fluid capacity over stock. It also features a new OEM CDF drum assembly, a new OEM F Clutch Cylinder Trashcan, and a new SunCoast 10L1000 Valve Body \u0026amp; Pump Assembly. The transmission includes an expanded capacity 'E' drum with a billet apply piston, providing 29% more clutch capacity than OEM and 15% more than other aftermarket drums. This design minimizes deflection and coning, utilizing 4140 steel dowels instead of cast aluminum for improved durability. The 'F' clutch pack has also been upgraded with 25% more capacity, and the 'D' clutch benefits from GPZ friction material for higher friction coefficients and increased torque capacity.\n\nThis transmission is designed for 2020-2024 GM 2500 and 3500 trucks equipped with the 6.6L Duramax L5P engine. Fitment includes specific model years and configurations: 2020-2021 Chevy Silverado 2500\/3500, 2020-2021 GMC Sierra 2500\/3500, 2022 Chevy\/GMC 2500\/3500, and 2023-2026 Chevy\/GMC Silverado\/Sierra 2500 HD\/3500 HD. The Pro-Loc Valve Body addresses key issues within the 10L1000 transmission, offering a multifaceted approach beyond simply increasing line pressure, suitable for demanding driving environments like heavy towing, hauling, and performance use.","brand":"SunCoast Performance","offers":[{"title":"Default Title","offer_id":52866414412088,"sku":"SC-10L1000-CAT3-4WD-LC","price":10649.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687701995.jpg?v=1787907471","url":"https:\/\/store.motormia.co\/products\/category-3-transmission-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
