Our Porsche Gearbox Service Protocol
Dealer-level PIWIS-based procedure:
1. PIWIS Live Telemetry & PDK Analysis
Clutch slip RPM per sub-transmission, clutch fill pressures, solenoid duty, temperature history, and adaptation counters — beyond generic OBD-II.
2. Mechatronic Repair & Calibration
- Solenoid test, ultrasonic clean, individual replacement.
- Pressure-sensor and TCU board evaluation.
- Valve body hydraulic overhaul.
3. PDK Clutch Pack Rebuilds
OEM friction plates, seals, bearings, dual-mass flywheel inspection, and clutch kiss-point calibration for high-mileage or track-driven cars.
4. Correct PDK Fluid & Filter Service
Porsche-spec PDK clutch and gear oils (separate circuits where applicable), filter replacement, temperature-controlled leveling (40°C), and wear-counter reset.
5. Clutch Teach-In & Adaptation Road Test
Clutch bite-point teach-in, fill-pressure relearn, and defined adaptation drive cycles to restore factory shift feel.
