The 2020, 2021, 2022, and 2023, 2500 and 3500 HD Chevrolet Silverado and GMC Sierra equipped with the L5P Duramax and 10-Speed Allison 10L1000 transmission are known for their smooth shifts and outstanding performance while towing. However, it leaves something to be desired when it comes to shifting in high performance applications. It can fall behind due to its drawn-out shifts and weaker clutch holding strength. Performance focused customers complain about how and when it shifts citing time between shifts and dramatic de-fuel as major areas of concern. Also, the factory tune isn't intuitive. It doesn't drop a gear and go when you want it to and we've found that it can benefit from several improvements.
DuramaxTuner's Custom TCM tuning will decrease time between shifts and improve 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 RPM range to utilize all of its potential power. 10-Speed transmission tuning can be utilized with and without a RatioTek shift kit installed.
Changing the factory calibration is especially important when you modifying your truck and/or installing custom ECM Tuning. Custom TCM Tuning gives you quicker shift changes, smoother operation, and a better overall driving experience when increasing your truck's performance.
