Cool Porsche PDK Transmission

The Porsche PDK transmission system from Porsche stands for Porsche Doppel Kupplungs getriebe (Porsche-Doppelkupplungsgetriebe). The PDK is basically what Porsche like to call its Dual-Clutch transmission system. Though the Dual-Clutch transmission is not new to automobiles, the system on the Porsche seems to be a few notches ahead as compared to the rest. The PDK transmission system eliminates one of the major drawbacks of the traditional automatic transmission in the form of eliminating the delayed response or lag experienced in power delivery.

The PDK Transmission system works instantly on engaging the gear on the push of the throttle. The PDK system was initially developed for racing applications, but its unmistakable benefits have seen it appear on production cars. The PDK system contrary to the traditional automatic transmission uses a clutch, well actually two clutches to be precise. There is one clutch which engages gears like the reverse, first, third, fifth and seventh, the second clutch engages gears second, fourth and sixth. So at any given point of time the car can instantly select one higher gear or one lower gear with the help of an electronically controlled actuator valve that actuates the correct clutch position. The presence of the physical clutch ensures instant response unlike having to wait for the transmission to match the engine rpm. The clutches are also immersed in oil and this highly reduces clutch wear and also helps in transfer of heat more effectively, leading to longer clutch life.
