While the factory component works fine for basic everyday driving applications, it leaves a lot to be desired for high horsepower and torque applications. Luckily for you, PPE has the answer with their Billet C-2 Clutch Hub! Developed for increased strength over stock, this aftermarket clutch hub ensures a more efficient power transfer which results in improved acceleration, better towing capabilities, and enhanced overall performance of the truck. The rigidity of the billet C-2 hub also helps minimize flexing, promoting consistent and reliable operation each time you get behind the wheel.\u003c\/p\u003e\n\u003ch4\u003eDurable Construction for High-Performance Applications\u003c\/h4\u003e\n\u003cp\u003ePPE developed their C-2 Clutch Hub using billet steel to ensure a perfect fit, form, and function on your GM 6.6L Duramax.

If you've modified your engine for higher horsepower and torque output, the Billet C-2 Hub will handle it without even breaking a sweat. When it comes to installation, this hub mounts directly in place of your existing components to make for a straightforward job you can complete at home.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020 GM Silverado\/Sierra 6.6L Duramax 2500HD\/3500HD with Allison Transmission 1000\u003c\/p\u003e","brand":"PPE","offers":[{"title":"Default Title","offer_id":49526782001436,"sku":"PPE128020200","price":719.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/ppe_128020200__90085.jpg?v=1722345445"},{"product_id":"ppe-128051420-deep-transmission-pan-20-26-gm-duramax-ford-superduty-with-allison","title":"PPE 128051420 Heavy Duty Cast Deep Transmission Pan for 10L1000 Transmission | 2020-2026 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax L5P","description":"\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFits 2020-2026 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax.\u003c\/li\u003e\n\u003cli\u003eIncreases transmission fluid capacity by 1 gallon.\u003c\/li\u003e\n\u003cli\u003eLowers transmission fluid temperatures for longer life.\u003c\/li\u003e\n\u003cli\u003eCast aluminum fins improve cooling efficiency.\u003c\/li\u003e\n\u003cli\u003eInternal heat sinks reduce fluid slosh and heat.\u003c\/li\u003e\n\u003cli\u003eReinforced flange gussets add strength and durability.\u003c\/li\u003e\n\u003cli\u003eIncludes stainless drain plug with Neodymium magnet.\u003c\/li\u003e\n\u003cli\u003eMagnetic check port plug captures harmful metal debris.\u003c\/li\u003e\n\u003cli\u003eViton O-ring seals resist leaks under high heat.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty cast aluminum construction for long service life.\u003c\/li\u003e\n\u003cli\u003eHelps protect expensive transmission internals from wear.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eKeep Your Allison Running Cooler And Stronger\u003c\/h4\u003e\n\u003cp\u003eWhen you put your truck to work, heat is the enemy that quietly wears down your transmission. The PPE Heavy Duty Cast Deep Transmission Pan is designed to fight back by adding a full extra gallon of fluid capacity, which lowers operating temperatures and extends fluid life. It is built from rugged cast aluminum, giving you a serious upgrade in both strength and cooling compared to the thin factory pan. The fins on the outside of the pan catch underbody airflow to help shed heat while the internal heat sinks keep fluid stable even when you are hauling heavy or climbing steep grades. PPE also thought ahead by adding powerful magnetic drain and check plugs that pull harmful metal shavings out of the oil before they can circulate through your transmission. That means better protection for the 10L1000 inside your Duramax-powered Silverado or Sierra. If you want your Allison to keep its reputation for reliability while working harder and lasting longer, this is one upgrade you will not regret.\u003c\/p\u003e\n\u003ch4\u003eBuilt To Protect The 10L1000 From The Inside Out\u003c\/h4\u003e\n\u003cp\u003eThe PPE Heavy Duty Cast Deep Transmission Pan for 2020-2026 GM Silverado and Sierra 2500HD and 3500HD models with the 6.6L Duramax is engineered with both durability and heat control in mind. Constructed from A356.0-T6 cast aluminum, it offers far greater strength and heat dissipation than a stock stamped steel pan. The design incorporates .75-inch external fins that take advantage of underbody airflow, while internal heat sinks reduce fluid sloshing and help stabilize temperatures under load. With the added gallon of capacity, the transmission fluid not only runs cooler but also maintains its protective qualities longer. PPE includes a stainless steel magnetic drain plug and a magnetic check port plug, both equipped with Viton O-ring seals to prevent leaks and capture metal particles before they can damage internal components. Reinforced flange gussets provide additional structural support, making the pan resilient against flex and vibration. Backed by a limited lifetime warranty, this transmission pan is a complete upgrade that enhances both performance and longevity of the Allison 10L1000.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e 2020, 2021, 2022, 2023, 2024, 2025, 2026 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax L5P w\/ 10L1000 transmission\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFits 2020-2026 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax 10L1000 transmission.\u003c\/li\u003e\n\u003cli\u003eAdds about 1 gallon of extra fluid capacity.\u003c\/li\u003e\n\u003cli\u003eLower fluid temps help extend transmission life.\u003c\/li\u003e\n\u003cli\u003eCast aluminum design is stronger than stamped steel.\u003c\/li\u003e\n\u003cli\u003eExternal fins and internal heat sinks improve cooling.\u003c\/li\u003e\n\u003cli\u003eMagnetic drain and check plugs capture metal debris.\u003c\/li\u003e\n\u003cli\u003eUses Viton O-ring seals to resist heat and leaks.\u003c\/li\u003e\n\u003cli\u003eCompatible with OEM transmission gasket for easy install.\u003c\/li\u003e\n\u003cli\u003eReinforced gussets prevent flange flex and warping.\u003c\/li\u003e\n\u003cli\u003eOptional port allows installation of a temp sensor.\u003c\/li\u003e\n\u003cli\u003eCovered by PPE’s limited lifetime warranty.\u003c\/li\u003e\n\u003cli\u003eProduct images may be representative.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0611\/8539\/2883\/files\/128051400-Deep-Transmission-Pan_Install-Guide-R1025.pdf?v=1761009783\" target=\"_blank\" rel=\"noopener\"\u003e\u003cstrong\u003eInstall Instructions\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"PPE","offers":[{"title":"Default Title","offer_id":49526983360796,"sku":"PPE128051420","price":377.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/128051420-4small_1200x_519ccbf0-309d-4191-b363-857dc8ac9343.webp?v=1788286073"},{"product_id":"duramax-tuner-dm1mo1372082000-pre-tuned-t93-tcm-replacement-2020-2023-gm-duramax-66l-10-speed-transmission","title":"Tuner DM1MO1372082000 Pre-Tuned T93 TCM Replacement | 2020-2023 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax L5P with 10-Speed Allison Transmission","description":"\u003cp\u003e\u003c\/p\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e \u003cul\u003e \u003cli\u003eSuperior shifting and drivability\u003c\/li\u003e \u003cli\u003eElevated shift points for larger tires\u003c\/li\u003e \u003cli\u003eAllows truck to feel more powerful\u003c\/li\u003e \u003cli\u003eGet best fuel economy possible\u003c\/li\u003e \u003cli\u003eEnsure engine is operating in preferred rev range\u003c\/li\u003e \u003cli\u003eQuicker shifts\u003c\/li\u003e  \u003c\/ul\u003e  \u003ch4\u003eTuned Transmission for Elevated Performance and Durability\u003c\/h4\u003e  The 10-Speed Allison Transmission in your 2020-2023 GM Duramax 6.6L L5P is decidedly an upgrade over the 6-speed Allison, however it still has plenty of room for improvement.

The SunCoast SC-10L1000-PVB Valve Body and Pump Kit is designed to turn that weak link into a real asset. From heavy towing to aggressive street driving, this setup delivers firmer shifts, stronger clutch holding power, and better overall control without sacrificing drivability! SunCoast takes a thoughtful approach here, improving oil flow and pressure in the areas that matter most instead of simply cranking up line pressure and hoping for the best. The result is a transmission that feels more confident under throttle and far more stable when torque demand spikes. Lockup happens quicker and cleaner, reducing unnecessary slip that can quietly kill the converter clutch over time. If your 2020-2026 Silverado or Sierra 2500HD or 3500HD sees real work or real power, this upgrade gives your transmission the backup it deserves.\u003c\/p\u003e\n\u003ch4\u003ePrecision Oil Control Designed For High Demand Conditions\u003c\/h4\u003e\n\u003cp\u003eThe SunCoast Pro Loc Valve Body and Pump Kit for the 10L1000 transmission is engineered to address known stress points when power levels and load demands increase. Overall line pressure is increased by as much as 60 psi, improving clutch pack clamping force while a built-in bypass prevents excessive pressure above 420 psi. The torque converter lockup circuit is modified to reduce the time from initial apply to zero turbine slip, which significantly improves clutch longevity. Lube circuit pressure is raised from a factory 6 psi to 20 psi, increasing oil flow to clutches, planets, and bushings to reduce heat buildup. SunCoast also recalibrates the regulator valve circuit, lowering the pressure required for full clutch engagement from 120 psi to 80 psi. This change shortens shift times and reduces frictional heat in critical clutch packs, especially the F clutch.
