5G-Tronic, 7G-Tronic, 9G-Tronic
AutoUpgrades provides precision calibration for Mercedes-Benz automatic transmissions, including the 5G-Tronic, 7G-Tronic, and 9G-Tronic families. Our transmission tuning is based on OEM-level calibration principles, detailed control-logic analysis, and extensive validation across petrol, diesel, and AMG performance platforms.
These transmissions are widely used across the Mercedes-Benz range, from daily drivers to high-output AMG models. Our calibration approach focuses on improving shift quality, torque handling, and drivability while preserving the durability and refinement Mercedes engineers designed into each gearbox.
Why Choose AutoUpgrades
Torque Limit Alignment: Internal torque thresholds recalibrated to accurately support increased engine output while retaining factory protection strategies.
Refined Shift Behaviour: Optimised shift scheduling for improved responsiveness, smoother transitions, and reduced hesitation.
Clutch and Pressure Control: Calibrated clutch pressure and fill behaviour for consistent shifts under load.
Sport and Manual Mode Refinement: Sharper response and more predictable gear selection where supported.
Mercedes 5G-Tronic Transmission Tuning (722.6)
The 5G-Tronic (722.6) is a robust five-speed automatic used extensively across Mercedes-Benz petrol and diesel models. Despite its age, it remains highly capable when correctly calibrated. Our 5G-Tronic tuning focuses on improving shift response, torque capacity, and drivability while preserving the gearbox’s well-known durability.
Mercedes 7G-Tronic Transmission Tuning (722.9)
The 7G-Tronic (722.9) introduced faster shifting and improved efficiency across a wide range of Mercedes vehicles, including AMG models. Our 7G-Tronic transmission tuning refines shift timing, pressure control, and torque management to deliver cleaner shifts and better response, particularly when paired with engine performance upgrades.
Mercedes 9G-Tronic Transmission Tuning (725.0)
The 9G-Tronic (725.0) is Mercedes-Benz’s modern nine-speed automatic, designed for efficiency, smoothness, and high torque capability. Used across newer petrol, diesel, and performance platforms, our 9G-Tronic calibration improves shift consistency, drivability, and torque handling while maintaining the refinement expected from Mercedes-Benz.
Each calibration is developed and validated against the specific drivetrain configuration, accounting for engine output, vehicle mass, and intended use case.
At AutoUpgrades, Mercedes-Benz transmissions are treated as integrated, precision-engineered systems. Our calibration approach ensures predictable torque transfer, consistent shift behaviour, and long-term reliability, delivering a transmission that performs exactly as intended, only better aligned with real-world performance demands.
