![]() These transmissions blend good old gearbox mechanicals with electro-mechanical or electro-hydraulic actuators, electrical motors, and control electronics. At the appropriate RPM, that clutch is engaged and the other one is disengaged, resulting in a gear change. When one clutch is engaged and driving the car on one gear, the gearbox can select the next gear (one higher or one lower) on the other clutch, but with that clutch disengaged. Each clutch drives a separate set of gears, with one clutch serving the odd-numbered gears and another the even-numbered gears. It is a type of transmission that has two clutches to drive separate gears. While this thread focuses on this model of transmission, many principles are equally applicable to other dual-clutch transmissions, such as the Volkswagen Direct Shift Gearbox (DSG) DQ200 and DQ250. Given the likelihood of this transmission becoming more popular on our roads, I've put together this thread to discuss how this particular model of transmission works. However, it is only now that Ford are actively pushing this transmission option, both in the Figo/Aspire, as well as by way of increased supply for the EcoSport. This transmission was previously offered in the Fiesta between 2011-2014, and is also offered in the EcoSport since 2013. ATF service is imperative to these gearboxes since they are highly sensitive and depend on hydraulics to operate properly, though with the help of apps, keeping up with maintenance isn't so bad.Ford India has launched the Figo and Aspire with the option of a dual clutch 6-speed automated gearbox, known as the PowerShift transmission. Since these transmissions have so much to offer, they evidently require more service than traditional automatic gearboxes. ![]() The drawbacks of sequential transmissions are few, though some exist. Because these gearboxes are highly efficient, it results in excellent performance on and off the track. Since dual-clutch transmissions are performance-oriented, what many people often overlook when shopping for such gearboxes is the great mileage that comes with it. This is crucial in performance scenarios where you need every ounce of horsepower planted onto the ground at all times. With the flawlessness of the shifts, missing a gear is never in the equation. Courtesy of the dual-clutch design, the next gear is always on deck, resulting in quicker and faster gear shifts than any manual transmission. ![]() One of the best things to come from these automated manual transmissions is the insanely fast gear shifts. Here are some of the quirks and drawbacks of a dual-clutch transmission. Like most automotive features, there are pros and cons to each added component. Since a driver takes 0.2 seconds for an upshift on average, saving every second counts in performance scenarios. Furthermore, like engine control units (ECUs), DCT transmissions can be tuned to increase their performance-by providing the driver with quicker and smoother gear changes. This is courtesy of a two-clutch system that's responsible for their odd and even gear sets. Unlike manual transmissions, DCTs have impeccable shifting ability in terms of timing and consistency. DCTs don't engage by themselves like those transmissions with torque converters, forcing the car to roll back on hills like a manual transmission. The two-clutch system in a DCT transmission is what truly differentiates itself from a traditional automatic transmission. Because of this, they are commonly known as Automated Manual Transmissions (AMTs). Traditional automatic transmissions utilize torque converters and gear sets to operate, whereas DCTs utilize two clutches instead of one. DCT stands for dual-clutch transmission, which also is representative of its construction.
