Add TCU programming capability to your Alientech KESS3 Master with the Alientech TCU Protocol. Designed for professional workshops and tuners, this activation expands your KESS3 toolkit so you can work with supported automatic transmission control units—unlocking more services, more jobs, and more revenue from the same customer base.
With TCU access, you can support transmission-related work alongside engine tuning, giving your workshop a more complete calibration offering. It’s ideal for performance builds, drivability refinement, and supported transmission calibration tasks where the TCU needs attention.
