Transmissions have much longer service intervals compare to for example oil and filter changes, which is why they sometimes are overlooked.. But that does not mean that they are any less important, your transmission sends power to the wheels, so it is important to keep this vital part of your vehicle in good operating condition. At Mcilvain Motors, we offer fluid and filter changes for automatic, manual, and PDK transmissions. Changing this fluid at regular intervals will ensure a long life from your transmission, keeping it shifting, and operating smoothly. For PDK service, we use a PORSCHE factory PIWISII scan tool.
