TCM Tuning For 2024-2026 L5P T93 TCMs
The 10-Speed Allison found in your 2024, 2025 or 2026 6.6L L5P Duramax is known for its smooth shifts and great towing performance. However, when it comes to shifting in high performance scenarios it still leaves a bit to be desired.
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 a more optimized RPM operating range to increase the overall amount of power making it to the wheels. This 10-Speed transmission tuning can be utilized with or without a RatioTek shift kit installed.
