The 6-Speed Allison 1000 transmission used in the 2017, 2018, and 2019 2500 and 3500 HD Chevrolet Silverado and GMC Sierra equipped with the L5P Duramax earned their reputation for excellence largely because of the advanced electronic control provided by the TCM (Transmission Control Module). Changing that 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.
DuramaxTuner's Custom TCM tuning will decrease time between shifts and improve clutch holding capacity by increasing line pressure electronically.
