No mechanical system is per cent bulletproof, but as manufacturers increasingly use DSG transmissions it would appear that their failure rate is very low. On some older models owners have reported faults with DSGs such as noisy bearings or juddering from the transmission but these are generally few and far between. As DSGs are fully automated they are actually far less open to abuse than a traditional manual.
Other manufacturers also offer DSG-style transmissions but many of them use different names. Thinking of buying an automatic car? These are the best on sale Skip to Content Skip to Footer. DSG vs a conventional automatic So what are the differences between an automatic and a DSG, and is it better to buy one over the other? Cost of DSG gearboxes While some cars can only be ordered with a DSG gearbox, this type of transmission is generally offered as a cost option.
Just like a manual or automatic transmission, a DSG has different sized gears, with the largest gear providing drive to the lowest gear, so, first gear. There are two gear selectors which straddle the gear sets and one will control gears going up, and the other one controls the gears going down. The other one is from a standing start where people often say a DSG can jerk as it takes off. This is simply because, to preserve the clutches in the transmission, the mechatronics unit will disengage both clutches when the vehicle is stationary.
So, just like shifting from neutral into first gear with a conventional manual transmission car there can be a slight jerk as the clutches on the DSG reengage. For an example, read this test of the Suzuki Vitara. From a driving perspective, using a DSG is just like using a traditional automatic transmission in that you slot it into D for Drive and then, well, drive off.
But, there are a few things to bear in mind when driving a car with a DSG…. The key things to remember are around taking off from a standing start, driving slowly up a hill or inching forwards in traffic. All these things can cause wear and tear on the clutch usually the one engaging first gear in the transmission, whereas a conventional automatic has a torque convertor which is much better able to handle slow speed crawling.
Then, as you move from the brake to the throttle the transmission is still in neutral and will then engage once the throttle has been applied and, so, just like you would in a conventional manual you can get a slight jerk as first gear engages. So, as the owner of a car with a DSG, my advice is to let a gap build ahead of you and then step off the brake and onto the throttle and drive to the next stop, rather than constantly inching forward.
What about if I want to get sporty? But, ham-fisted driving can confuse a DSG and cause issues with the way it behaves. All this does is confuse the car into grabbing the opposite gear to the one you might want.
Seems odd that it was Porsche that first developed the semi-automatic transmission in the late s. Yep, the company synonymous with manual transmissions offered an automated manual transmission called the Sportomatic on the from , which had no clutch pedal the clutch was vacuum actuated when the gear shifter was moved and a torque convertor to keep it from stalling while idling.

For economic driving, it is irrelevant are you wasting fuel or potential energy, unless you are about to stop at the bottom. Shifting neutral is most likely to produce best fuel economy, but engineers do not design the cars to be operated this way; engaging the gearbox after reaching the hill bottom can really confuse the car to shift in weird gears, burning clutches.
I try to drive downhill on a power level where the speed accelerates, but very modestly. The other car I have will automagically switch to motor braking after a couple of seconds if I release the accelerator pedal, reducing speed. Are you sure that it is the flywheel?
Because if it the flywheel something really fishy could be wrong with your vehicle. Happy to help. The same happened to mine n we changed it but now the car jerks each time the gears change and its really hard to drive that way.. This site uses Akismet to reduce spam.
