Diagnostics, road test, mechatronics and clutch inspection, repair estimate.
We do not replace expensive parts blindly. Every automatic gearbox repair starts with thorough diagnostics, and the work plan and cost estimate are agreed before any work begins.
We discuss reported symptoms, driving conditions, vehicle service history and past repairs.
We perform computer fault scans, live pressure checks, physical inspection and a diagnostic road test.
We explain the underlying problem, outline necessary repairs, and provide an upfront itemized cost quote.
Upon your approval, we perform mechatronics repair, clutch replacement, flywheel change or oil service.
We execute basic software calibration and clutch adaptations, finishing with a verification road test.
Accurate verification of operating parameters before repair decisions
We retrieve logged DTC fault codes from the transmission control unit (TCM) using dedicated diagnostic tools.
We evaluate real-time hydraulic pressures, oil temperature, solenoid positions and clutch slip values.
We assess shift smoothness, kickdown responsiveness, downshift behavior and vibrations under load.
We check the gearbox housing for leaks, inspect driveshafts and inspect engine/transmission mountings.
We evaluate oil level, color, smell and check for metal shavings or burnt odor in the transmission fluid.
We provide an accurate diagnostic report and itemized quotation before any repair work commences.
Engineering differences, clutch designs and maintenance requirements
Widespread 7-speed dual-clutch transmission for smaller petrol and diesel engines. Features two separate fluid circuits: gear oil for mechanical components and hydraulic fluid for mechatronics. Sensitive to clutch wear in dense city traffic.
Classic robust 6-speed design with wet multi-plate clutches immersed in an oil bath. One shared oil circuit for gears, clutches and mechatronics. Exceptionally durable when serviced regularly with fresh oil and filter.
Modern, high-efficiency 7-speed gearbox engineered for MQB platform models. Features reduced internal friction losses, on-demand secondary oil pump, and smooth shift characteristics under varying loads.
Heavy-duty transmission built for demanding applications: high-power SUVs, performance sports cars and commercial transporters. Exceptional torque capacity and towing endurance.

Crucial preventive maintenance against expensive failures
Our workshop in Krakow (ul. Kolejarzy 7 and ul. Kierzkowskiego 24) is conveniently located for drivers from Podgórze, Łagiewniki-Borek Fałęcki, Bieżanów, Kurdwanów and Ruczaj, with fast access from the A4 motorway and S7 expressway.
The final cost depends on the exact fault and required work scope. Routine fluid service and software adaptation have one cost, whereas clutch pack renewal or mechatronics repair require itemized quotes. We always conduct diagnostics first and provide an upfront estimate for approval.
Common warning signs include jerking when starting or shifting from 1st to 2nd gear, delayed response when engaging D or R, clutch slippage, loss of even or odd gear sets, flashing PRNDS display, and the gearbox entering emergency limp mode.
Most common malfunctions – such as worn clutch packs, mechatronics valve issues, solenoid faults, or dual-mass flywheel wear – can be successfully repaired. The viability of repair is determined by internal mechanical condition during professional diagnosis.
Mechatronics is the electrohydraulic nerve center of the gearbox. It integrates the electronic control unit (TCU) with an intricate hydraulic valve body containing solenoids that precisely orchestrate clutch actuation and gear selection.
Yes. Following any intervention involving the clutch pack, mechatronics module, or oil replacement, a basic computer calibration and adaptation of clutch contact points and shift rod end-stops is mandatory.
Service intervals depend on the specific gearbox model, driving conditions, and vehicle manufacturer guidelines. For wet-clutch gearboxes, timely fluid renewal is vital for clutch and valve longevity. We verify exact recommendations via vehicle VIN.
DQ200 is a 7-speed gearbox with dry clutches designed for engine torque up to 250 Nm. DQ250 is a 6-speed gearbox with wet clutches bathed in oil, handling torque up to 350-380 Nm. They differ substantially in architecture, oil circuits, and maintenance needs.
Turnaround depends on the issue's complexity and parts availability. Initial computer diagnostics are performed promptly by appointment, whereas extensive mechanical rebuilding typically takes from one to several business days.
Yes. We specialize in DSG and S-Tronic transmissions installed in Volkswagen Group vehicles: VW, Audi, Škoda, SEAT, and CUPRA, as well as selected conventional torque-converter automatics in passenger cars and vans.
Yes, always. We never replace costly parts blindly. The initial step is rigorous electronic fault reading, live sensor data analysis, and road testing. Only after confirming the root cause do we present our estimate.
