Automatic Transmission Control Unit Coding
Automatic Transmission Control Unit Coding
Electric and hybrid Mercedes-Benz vehicles with multi-mode transmissions depend on electronic control units to shift seamlessly and manage torque flow. After repairs, replacements, or software faults, these units require precise coding to perform optimally. AT Technicians offers dealer-level coding for transmission control units (TCUs) in hybrid Mercedes-Benz models. We begin by reading the TCU’s current configuration, including adaptation values, firmware versions, and shift logic profiles. Using Mercedes-Benz Xentry and SCN coding tools, we reset, reprogram, or update the TCU to restore its learning parameters. This allows the gearbox to adapt smoothly to the driving style, engine characteristics, and road conditions. Improper TCU programming can cause rough shifts, delayed responses, or transmission fault lights. Our technicians ensure the unit is synchronised with the ECU, hybrid drive system, and battery management. We also conduct road tests to fine-tune performance and validate smooth operation.
