How does dsg gears work




















Email address:. One question I have is whether hill hold assist is supposed to work in reverse on DSG equipped Skodas, specifically a Superb with the now infamous 2. I laughed. Thanks Isaac…. Slow speed manoeuvring in a car-park, 3 point turns, bumper-to-bumper traffic, 3 point turn etc was just terrible. Yeah, mostly quite good once going. What are you main issues? As far as I can tell, the main issue is when people try and drive them like a conventional automatic transmission.

This is a very interesting article about DSGs and the reasoning behind their behaviour. I now have a better appreciation of them. When upshifting, the engine speed needs to be slowed down because the driveshaft is now rotating slower at a higher gear. The prediction is based on a the position of the transducers and a look up table based on a recording and shaping of trials down using geartrain set-ups in the laboratory and real world trials using volunteer drivers on cars.

The problem is that some car manufacturers set up the transmission to work like a conventional automatic, so the gearbox keeps going into and out of gear, rather than working like a person using a manual, which tend to let the car roll forward with the clutch in and then engage when the traffic is clear.

Makes better sense when you first of all start reading about how manual and traditional automatic transmissions work. Pretty awesome tech once you have that background knowledge and it really makes sense to drive a car with one. Absolutely JR Clever transmission that gets a bad wrap… mostly by journos who expected it to behave like a regular automatic transmission. Select personalised content.

These operate a pair of input shafts, and the ascending gears sit on different shafts. This is how a dual-clutch gearbox is able to shift so quickly.

When you're in a given gear, the next gear is pre-selected and ready to go when you need it. Our hosts also explain how the shifts can sometimes seem a bit jerky. The numerous clutch plates sit in an oil bath and keep the whole assembly moving you along. It's both a compact and complex system. Still, with the help of the hosts, it's easy to wrap your head around a dual-clutch gearbox. Dual-clutch gearboxes can be heavier too and, in some cases, be slightly less fuel-efficient than manual gearboxes - this, however, will depend on the car you buy.

Releasing the brake in the reverse or drive will mean the car starts creeping backwards or forwards respectively - this is deliberate, as it makes low-speed manoeuvring easier. In most cases, both a six-speed and seven-speed DSG gearbox will be as reliable as any other gearbox. Some owners have reported that older gearboxes have been prone to the occasional failure, but the newer boxes seem to have overcome these. However, all mechanical parts can wear down over time if not properly maintained or replaced, and automatic gearboxes are more complicated than manuals.

You can also choose a CVT or, in some cases, an automated manual. On lower-powered cars, this can mean the engine is noisily revving unnecessarily.

Automated manuals, on the other hand, can sometimes be slow to change gear, and jerky too. Ford, for example, calls it a Powershift gearbox.
