A technology that brings the fundamentals of motorcycles - the joy of riding and control, to a whole new level.The DCT (Dual Clutch Transmission) technology by Honda. The world's first in motorcycles.Welcome to the world of DCT. My first DCT was a 6-speed Cee'd 1.6 petrol, which I bought in 2017, and apart from a sticky valve which was fixed under warranty, I had no problems in some three years, driving around 17,000 miles. I now have a Niro HEV with a similar transmission and that now has a little under 6,000 faultless miles on the clock.
The 7-speed dual clutch transmission makes especially sporty driving performance possible: direct drive and lightning-fast gear changes without interrupting the shear force. The car 'sits right on the gas'. It also achieves fuel economy better than that of a manual transmission thanks to its excellent fuel efficiency.

Many drivers treat their car’s dual-clutch transmission in the same way that they would drive a car that had an automatic transmission. But, a dual-clutch transmission is more like a manual transmission than automatic. And if you don’t treat it properly, you could permanently damage it.
Some of your current driving habits could ruin a dual-clutch transmission. If you’re doing any of the following and your car has a DCT, cut it out!

Habits to avoid so you don’t ruin a dual-clutch transmission
Stop taking your foot off the brake
If you have a tendency to let your DCT sit without applying the brakes, such as waiting in traffic or at the foot of an incline, you could be wearing out the clutch pack. When the brakes aren’t applied, some DCTs will make the clutches continually slipping to keep you in place. This depends on how your transmission operates, but you could be putting extra heat and wear on the clutch pack.
Stop putting the car in neutral
Those who are used to driving stick shifts might have a habit of putting their car in neutral when they’re fully stopped at an intersection. You don’t need to do this with a dual-clutch transmission. The car will intuitively release the clutches when you’re braking, so there’s no point switching out of Drive.
If you do ever put the car in neutral, keep the brake depressed when shifting into and out of neutral to protect the clutch.

Stop launching improperly
In sportier cars with dual-clutch transmissions, drivers like to launch from a stand-still, but doing so incorrectly can severely damage the gearbox and clutch disks. Don’t hold the brake pedal while you’re revving the gas because the clutch will take damage trying to move the car while you’re fighting it with the brakes. In general, never accelerate the engine when the brakes are applied.
Mypower driver. Stop keeping the car in place by accelerating
If you’re sitting on an incline, don’t repeatedly tap the acceleration pedal to keep your position. The same goes for putting the car in reverse and accelerating backward to stop from rolling down a hill. Both practices will quickly overheat the clutch. Use the brakes instead.
Clutch behavioral logic and functions vary from manufacturer to manufacturer, so research your specific model to find out how to properly operate. Your car’s owner’s manual will have a lot of information on proper handing to not ruin a dual-clutch transmission.

Kia gave a little glimpse into the near future when they showed off their new 7-speed dual-clutch transmission (DCT) at the Geneva Motor Show.
This new state-of-the-art automatic transmission is a first for Kia, as they look to deliver improved fuel efficiency, improved performance, and a sportier driving feel to their vehicles. Amd & ati usb devices driver.
The idea is to use this transmission to replace the existing 6-speed automatic that is delivered as an option on a number of different Kia models.
The new seven-speed automatic gearbox (DCT) takes the best of manual and automatic transmissions and combines them to deliver faster gear changes.
Update: first Kia to be available with new 7-speed DCT is the 2016 Optima LX 1,6T.

Improved Performance And Fuel Efficiency
The goal of the engineers as they designed the transmission was to deliver a 7% increase in fuel efficiency and a 5% improvement in acceleration over the existing 6-speed automatic transmission.
Kia’s research and developmnet team has also been focusing on NVH through the development process. The use of an external damper means that the new automatic gearbox is a lot more refined.

A pair of dry clutches are used in the DCT, each of which has an electric motor-driven clutch actuator to help improve fuel efficiency. There are also two gear input shafts used in the odd and even gear ratios.
This set-up means that the DCT is able to immediately jump to any of its seven gears, or be able to do it sequentially, depending on what the driver needs at any given time.
The automaker’s new DCT unit is able to minimize the amount of torque lost during shifting by employing continuous power delivery, which also helps make each gear change incredibly smooth.

The 7-speed transmission offers wider ratio coverage than the 6-speed alternative, which in turn results in a much improved fuel efficiency rating.

Kia has penciled in 2015 as the year in which this transmission will start appearing in their cars.
