Transmission tuning for your Mercedes-Benz A Class

Supported transmission software is calibrated around the exact W177 powertrain, engine output and intended use.

Electronically controlled transmission

Transmission-specific performance software

Automatic, dual-clutch and electrohydraulic automated-manual gearboxes use different control strategies. Only the route matching the fitted transmission applies; CVT and other electronic transmission support is assessed separately.

Torque-converter automatic

Automatic gearbox tuning

Conventional automatic transmission software can be recalibrated around the engine output, converter characteristics and intended use.

  • Honest torque limitsRaise supported torque limits in the transmission calibration instead of spoofing or hiding engine torque from the control unit.
  • Pressure managementAdjust line or clutch pressure within safe limits to improve holding force and support increased torque.
  • Shift speed and responseReduce shift time and improve response to throttle and paddle requests where the hardware safely supports it.
  • Shift mapsChange upshift and downshift strategy for load, gradients, driving modes and driver demand.
  • Manual-mode controlAlter kickdown and forced-upshift behaviour where supported while retaining essential protection strategies.
  • Rev matchingRefine throttle blips and torque intervention for smoother, more responsive downshifts.
  • Launch behaviourConfigure supported launch parameters and brake-and-throttle operation for suitable applications.
  • Driver informationEnable available gear-display or mode information where the vehicle and controller support it.

Available options depend on the exact transmission software, hardware limits and mechanical condition.

Dual-clutch transmission tuning

Dual-clutch tuning coordinates two clutches, pre-selected gears and engine torque intervention rather than treating the unit like a conventional automatic.

  • Clutch pressure and capacityRaise supported clutch pressure and torque limits to match the engine calibration without falsifying torque data.
  • Clutch and take-off controlRefine clutch engagement, take-off behaviour and anti-judder strategies where supported.
  • D, S and M programsCalibrate separate drive, sport and manual shift strategies around road or performance use.
  • Shift and paddle responseImprove upshift, downshift and paddle-command response while coordinating the required engine torque reduction.
  • Shift points and overridesAdjust RPM setpoints, kickdown and optional automatic upshift/downshift behaviour.
  • Launch controlConfigure supported launch RPM, response and mode behaviour for the vehicle and available grip.
  • Cooling and thermal strategyApply available clutch-cooling and thermal-management changes for suitable higher-load applications.

Electrohydraulic automated-manual tuning

These are single-clutch manual gearboxes operated by hydraulic actuators. Their calibration and service requirements are different from both DSG/DCT and torque-converter automatics.

  • Clutch bite-point setupSet and verify the PIS or kiss point after appropriate clutch, actuator or hydraulic work.
  • Clutch engagement learningCarry out supported clutch self-learning and engagement calibration using the correct manufacturer procedure.
  • Gear-structure learningPerform supported gear-selection and engagement self-learning after relevant repair or adjustment.
  • Hydraulic diagnosisCheck pump, accumulator, pressure, actuator movement and leakage before attempting calibration changes.
  • Shift and take-off refinementWhere software support exists, refine initial clutch engagement, shift response and automatic-mode gear selection.
  • Clutch-wear protectionBase calibration decisions on measured clutch condition rather than using software to conceal wear or hydraulic faults.

Support varies significantly across Fiat, Alfa Romeo, Maserati and Ferrari applications and must be confirmed from the gearbox and control-unit identification.

Servicing, repair & adaptation

Transmission servicing and adaptations for your Mercedes-Benz A Class

Fluid servicing, diagnosis and supported relearn procedures are considered together around the fitted transmission and its condition.

Service and condition

Maintenance, diagnosis and repair

Transmission fluid service

Drain-and-fill, filter or sump service, and controlled fluid exchange are considered according to gearbox type and condition.

Transmission diagnostics

Leaks, noises, selection problems, judder, slipping, warning messages and shift quality are assessed before work is recommended.

Filters, sumps and seals

Serviceable filters, sump assemblies, sleeves, seals and level procedures are matched to the fitted transmission.

Cooling and repair support

Temperature, cooling, pan and repair options are reviewed for suitable performance applications or confirmed transmission faults.

Manufacturer software updates

Available control-unit updates and manufacturer revisions are checked as part of appropriate maintenance, diagnostic or repair work before modified software is considered.

After appropriate workshop work

Adaptation and relearn

Adaptation reset and relearn

Adaptations are reset and relearned after appropriate service, repair, software or calibration work - not used to disguise a mechanical fault.
