- Remove the underbody panel, drain the PDK transmission fluid. The clutch and gear fluids are the same, not to be confused with the final drive gear oil. There are two drain plugs for final drive gear oil due to the shaft bearings.
- Replace the PDK transmission pan and all the pan bolts. The genuine kit comes with new aluminum bolts. Note: The PDK transmission oil pan incorporates the filter assembly. All the PDK Transmission oil pan bolts (6.00mm x 25.00mm) are of aluminum construction. It is required to always replace aluminum fasteners, never reuse them.
- Torque all the aluminum oil pan bolts to 2.4nm. Install new drain plug that should come with the genuine kit (in early production cars the factory installed drain plug is plastic). Torque drain plug to 15nm -/+3nm
- Place masking tape (or bunch up a shop towel) on the seam of the oil pan to the transmission, directly under the fill Plug area to keep oil out of the Crevice/Seam mating area (The masking tape length should be roughly 6” long).
- Precondition PDK fluid by shaking the container of fluid for 10 minutes. Static fill the PDK transmission with fluid until it runs out of the fill-plug hole, leave the fill plug off for now.
- Connect a suitable scan tool and then set it up to monitor the PDK fluid temperature. Attention: Hot oil can scold!
- Start and run the engine in “Park”, immediately add fluid if it is not running out of the fill plug hole, carefully maintain this fluid level throughout the whole fill process.
- Cycle the shifter through all shift modes of R-N-D at least once, pausing for 1-2 seconds in each mode.
- Move the shifter selector into “Park” mode.
- Closely monitor the PDK fluid temperature. When the PDK fluid reaches the temperature of 30°C (86°F), you must command the vehicle utilizing a scan tool into the transmission “Fill mode”. The scan tool will not enter the “Fill Mode” until the PDK transmission oil temperature reaches 30°C(86°F), BUT at no higher than 40°C (104°F). PLEASE NOTE; this process must be expediently followed because the “Oil Fill” mode ends sharply after 5 minutes.
- Now fill the PDK fluid while the transmission is in the “Fill Mode”. Put the PDK fluid fill plug in and torque it to 27nm while the engine is still running.
- Remove the previously applied tape and then clean all the residual fluid off of the exterior surfaces.
- Turn the engine off.
- Reassemble the car as per the Workshop Manual in PIWIS TSI . Always consult with PIWIS TSI for latest info.
- As a recommendation only, it is best to check the rear wheel alignment on the Mid-Engine Sports Cars due to having the Chassis Strengthening Plate removed for the PDK fluid service.
NOTE: The Porsche factory recommended Service Interval for the PDK transmission fluid is every 60,000 miles. We advise this service every 40,000 miles for a healthier transmission and also for better shifting characteristics. Always consult with PIWIS TSI for latest information.
Transmission Pan/Filter Kit PN: 9G1.321.025.00 (This kit includes the drain plug and all the oil pan bolts)
Transmission Fluid PN: 000.043.207.30 (Usually requires roughly 4.5-5.5 Liters)
