{"product_id":"6-speed-conversion-kit-with-tcm-tuning","title":"6 Speed Conversion Kit with TCM Tuning","description":"The Calibrated Power 6 Speed Conversion Kit offers a significant upgrade for 2001-2005 LB7 and LLY Duramax trucks equipped with Allison transmissions. By adding a sixth gear, this kit achieves a 14% RPM reduction, translating to approximately 300 fewer RPMs during highway cruising.\n\nBeyond performance benefits, this kit enhances the driving experience by creating a quieter cabin interior with less exhaust drone at speed. Duramaxtuner calibrates the firmness and timing of shifts, ensuring smoother operation and better shift quality compared to the original 5-speed transmission. The conversion includes all-new components such as the valve body, wiring harness, and solenoids, along with custom TCM tuning tailored to your specific truck.\n\nFor proper order processing and to prevent delays, customers must provide their vehicle's VIN, tire size, and the type of turbocharger installed in the 'NOTES' field during checkout. This ensures the custom tuning and conversion kit are precisely matched to your truck's configuration. The kit is compatible with high idle controllers and features a gear indicator that functions with the Edge CTS monitor.","brand":"Duramax Tuner","offers":[{"title":"Default Title","offer_id":52687308652856,"sku":"DM1361070080900","price":1999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660683326.jpg?v=1784882467","url":"https:\/\/store.motormia.co\/products\/6-speed-conversion-kit-with-tcm-tuning","provider":"MOTORMIA","version":"1.0","type":"link"}
