For better results, you will want to wait for a larger gap in traffic before you take your foot off the brake to move forward. By having your foot on the brake and slowly creeping forward, your first gear clutch is not fully engaged, which means there is more wear on the transmission.Īlthough the clutch is designed to handle such driving behavior, pros suggest that avoiding this type of driving as much as possible will prolong the longevity of the DCT gearbox. DCT does provide you that sort of comfort but you still need to be aware that slowly inching forward in a dual clutch vehicle is not a good idea. Traffic jams are always frustrating but thanks to automatic transmissions you don’t have to feel the pain of engaging and disengaging the clutch manually. However, in a normal passenger car with DCT that is not equipped with launch control system, you will certainly not want to take the risk. As the speed of the engine increases, the vehicle will disengage the transmission if you are not moving forward. Some performance vehicles have systems in place (launch control) to prevent damage from launching your vehicle the wrong way. By doing so, the heat and tension generated will transfer to the clutch and cause damage. To do so, people often hold the accelerator and brake pedals at the same time for too long. Launching a car fast is a thrill in its own. When doing so, the engine and transmission run at slightly different speeds which result in a little slip between the clutch and the flywheel shortening its life span. Since the correct gear was not pre-selected, it will take some time for the vehicle to select the correct gear. This delay is a result of the vehicle pre-selecting a lower gear based on the usage of the brake. If you apply the brake before shifting up, you will experience a delay in shifting.

Suppose when you approach a red signal and the light turns green before you have enough time to stop. If you are engaging the brake and slowing down, the transmission will pre-select a lower gear. When you are speeding up with pressing the accelerator pedal, the dual clutch transmission will pre-select a higher gear. The throttle position, brake position and the speed are the main factors with which it determines when to shift the gears. The DCT gearbox has several entries to measure which gear to engage. No Downshift in Acceleration & Upshift During Braking By taking the pressure off the clutch, you will reduce the amount of heat, wear, and stress that is applied to the transmission. When you use brakes, the clutch is automatically disengaged. Using your brakes at each incline will work well in protecting your vehicle. Related: Paddle Shifters- How It All Started? Over the course of time, this behavior will cause serious damage to the clutch. So the force needed to maintain the position of your vehicle will put even more stress on the clutch– it will eventually heat up and start slipping. However in case of dual clutch transmission, the clutch itself attempts to hold the vehicle in place. When you are driving a conventional automatic vehicle, the spinning of the torque converter will hold the car in place, preventing it from rolling. If you drive a vehicle that has a dual clutch transmission, learning to handle inclines & slopes effectively is one of the biggest obstacles to overcome. Although the basic principle of this transmission is to simply shift gears, but since the mechanism of doing this job is different, there are a certain things you need to keep in mind. As the vehicle gains speed and the second gear is needed, the clutch is immediately engaged. When the first gear is engaged, the second gear on the other shaft is selected and is ready to be engaged. How Dual Clutch Transmission Works?įirst you should know how a DCT gearbox works? Basically it has two operating shafts, one for the odd gears and the other for even gears, and there are two separate clutches for each shaft, hence dual-clutch. But don’t worry you just have to keep below mentioned things in mind which will eventually benefit you in properly using a car with DCT gearbox, so read on. If you are not aware of how DCT works, you might end up in damaging the transmission of your vehicle due to incorrect driving practices. However there are a certain things that need to be kept in mind when you are driving a car with DCT gearbox. For long we have been accustomed to manual, conventional torque converter automatics or CVT (continuously variable transmission) but with the introduction of new players we are now embracing cars with DCT (dual clutch transmission) which is being offered with the likes of Changan Alsvin & Proton X70 etc.
