What is a PDK Transmission?

When it comes to transmissions, high end brand cars are always looking for the best technology and engine parts to put in their models. Porsche has done just that with their Porsche Doppel Kupplings (PDK) double-clutch transmission. What makes the PDK different from standard dual-clutch transmissions is that it uses hydraulically actuated wet clutch packs one enveloped around the other.

The PDK is broken down as such. One clutch connects reverse, the first, third, fifth and seventh gears, while the other handles the second, fourth and sixth gears. Instead of a clutch pedal on the floor, the PDK has an electronically controlled valve body that actuates the correct clutch when needed. The PDK system engages one clutch at a time. However, because gear sets alternate between clutches, as one disengages the other can engage in one fluid motion.

The PDK transmission system avoids damaging parts with launch control by effortlessly switching from one clutch to the other, as the system engages one clutch at a time. By doing this, the oil-soaked wet-clutches don’t overheat and wear out under pressure.
