Description

The Duramax Tuner DT1160030201002 is a transmission tune designed for 2017-2019 GM Silverado/Sierra 2500HD/3500HD trucks with the 6.6L Duramax L5P engine. This tune works with existing ECM tuning to provide smoother shifting and improved drivability, helping to put power to the ground more effectively. It increases line pressure for better clutch holding capacity and prevents short-shifting in performance applications.
