Introduction to Porsche PDK
At Rennen Porsche, we understand the concerns that come with owning a Porsche equipped with a PDK transmission. Whether you own a 911, Boxster, or Cayman, the PDK is a marvel of engineering, but like any complex system, it can encounter issues. Here’s a comprehensive overview to help you understand, diagnose, and address potential PDK issues with confidence.
Customer Concerns
Many of our customers share similar stories: transitioning from a manual to a PDK transmission brings up worries about repair costs and serviceability. With replacement costs exceeding $25,000, the misconception that PDK units are non-serviceable can be daunting. However, modern advancements have made these transmissions more repairable than ever.

Despite the complexity of the PDK, it is indeed serviceable. Independent shops like Rennen Porsche can undertake repairs that dealers often avoid. We provide specialized services that include the repair of various PDK components, such as solenoids and sensors, ensuring your Porsche runs smoothly without needing a full transmission replacement.
PDK Transmission Models
The ZF 7DT45 and 7DT70 are the primary models used in Porsche 911s, Boxsters, and Caymans from 2009 to 2016. While these models share many similarities, they do have variations in components and gear ratios, especially in the 911 Turbo models. Minor updates were introduced in 2013 for the 991.1/981.1 models, including additional cooling and sensor upgrades.
