REPLACEMENT T93 & TCM TUNING FOR 2020-2023 (L5P) 10-SPEED ALLISON TRANSMISSION W/ HP TUNERS HARDWARE AND CREDITS
The 2020, 2021, 2022, or 2023, 2500 and 3500 HD Silverado/Sierra equipped with the 10-Speed Allison transmission is known for their outstanding performance while towing. However, there are many complaints about how and when it shifts. Many customers gripe about the time between shifts and dramatic de-fuel. Also, the factory tune isn't intuitive. It doesn't drop a gear and go when you want it to and overall needs improvements.
DuramaxTuner's Custom TCM tuning will decrease the time between shifts and improve the clutch holding capacity by increasing line pressure electronically. This will make a more durable, better feeling, and better driving transmission. It can also help keep the engine in the ideal RMP range to utilize all of its potential power. 10-Speed transmission tuning can be utilized with and without a RatioTek shift kit installed.

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.
