For trucks equipped with larger turbochargers, \u003cstrong\u003ePPEI Transmission Tuning\u003c\/strong\u003e is crucial to return the engine to its proper RPM range, aligning it with the new turbo's torque curve.\u003c\/p\u003e\n\u003ch3\u003eOptimized Torque Converter Lockup\u003c\/h3\u003e\n\u003cp\u003eAlong with the improved shift points, PPEI refines the torque converter lockup strategy to deliver power to the ground more efficiently. This helps improve fuel economy by eliminating unnecessary slip in the torque converter — which also reduces heat in typical “unlocked” conditions.\u003c\/p\u003e\n\u003ch3\u003eIncreased Line Pressure for Greater Holding Power\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eLastly (and possibly the greatest benefit)\u003c\/strong\u003e is the increase in line pressure PPEI provides. Higher line pressure increases the transmission’s holding capacity by clamping the clutch packs together with more force. This allows tuned trucks — or trucks towing heavy — to enjoy added confidence, durability, and long-term performance.\u003c\/p\u003e\n\u003ch3\u003eInstallation Compatibility\u003c\/h3\u003e\n\u003cp\u003eThis tuning package can be installed using the following supported hardware:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEFILive AutoCal V2\u003c\/li\u003e\n\u003cli\u003eEFILive FlashScan V2\u003c\/li\u003e\n\u003cli\u003eEFILive AutoCal V3\u003c\/li\u003e\n\u003cli\u003eEZ LYNK AutoAgent 2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePPEI Transmission Tuning\u003c\/strong\u003e is the proven solution for maximizing your Allison’s potential — delivering smoother shifts, reduced heat, improved drivability, and increased reliability for tuned and towing applications alike.\u003c\/p\u003e","brand":"PPEI Tuning","offers":[{"title":"Default Title","offer_id":51231855706395,"sku":"PP-T87-TT","price":284.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0962\/5757\/3147\/files\/2015.5_-_2016_GM_6.6L_LML_Duramax_T87_Engine_Tuning_by_PPEI_800x_59f627d8-29e8-4ea9-8de3-935b669e40a3.webp?v=1765308096","url":"https:\/\/wwmperformance.com\/products\/2015-5-2016-gm-6-6l-lml-duramax-t87-allison-transmission-tuning-by-ppei","provider":"WWM Performance","version":"1.0","type":"link"}
