Allison 10-Speed Transmission Tuning
The 10-Speed Allison found in your 2020-2023 L5P Duramax is known for its smooth shifts and great performance while towing. However, it still leaves a bit to be desired when it comes to shifiting in high performance senarios. It can fall behind due to its drawn-out shifts and its weaker clutch holding strength. Changing the factory calibration is especially important when you modify your truck and/or install ECM Tuning. Custom TCM Tuning gives you quicker shift changes, smoother operation, and an overall better driving experience.
