Description
The DIESELR EFI Live Transmission Tune File (2019–2024 Cummins 6.7L AISIN) is engineered for Cummins owners who expect more than stock limitations. This transmission tune keeps your AISIN gearbox fully aligned with your ECM tuning, delivering stronger shifts, improved throttle response, and precise power transfer.
Unlike factory programming that short-shifts and lugs, this tune refines shift logic to keep your Cummins 6.7L in its power band. Whether towing heavy, daily driving, or running a bigger turbo setup, it eliminates the weak points that cost you efficiency and drivability.
