This means that longevity-wise, TC failures are very few and far in between. In addition, TC transmissions are generally more robust and are less complex mechanically compared to DCTs. Being stuck in traffic is also less of a chore in a TC-equipped car, as the crawling characteristics of the transmission is seamless and smooth, because you can just ease off the brakes to get the car moving, unlike DCT-equipped cars.
Moreover, TCs have excellent low-speed behaviour. In fact, you can’t really call modern TCs ‘slushboxes’ anymore, because there’s nothing slushy about these 'boxes now. All this while having less power loss, faster shift-times and better response. Today, torque converters still retain its inherent smoothness, be it in traffic or while cruising.

It was commonly referred to as a ‘slushbox’ because in its early days, TCs were not all that fast-shifting, plus it sapped a lot of power from the engine, thus blunting acceleration and response. Torque converter automatics have come a long way since its inception. ZF's 8HP 8-speed torque converter, the best of its kind in the world Because of this, DCTs will be here for the foreseeable future. That’s why, you still see DCTs in high-performance brands like Ferrari, Porsche, and McLaren, because shift speeds are all-important in their quest to extract faster lap times and 0-100 km/h sprints. From an engineering standpoint, DCTs are just plainly the faster transmission, in a way that no TCs can match. Which brings me to why the DCT transmission is here to stay speed. Porsche's PDK DCT transmission is so good, you can concentrate of squeezing out that last tenth of laptime Having tested the DCT-equipped X70 myself, I can attest that it brings a sprightlier driving experience. It was lurchy, ponderous, and jerky.Ĭuriously though, Proton has gone the opposite direction with the X70, with the DCT replacing the TC transmission. All I can say from experience is, the Powershift transmission wasn’t a very good representation of DCT transmissions. Still, there has to be a reason why Ford abandoned its DCT endeavour, so much so that none of the cars it sells in Malaysia now comes with a DCT. Personally, in my time owning the Golf GTI, the DCT performed flawlessly. There have been many conflicting stories about ownership experience of DCTs. The most common criticism that is levelled at the DCT, is that it is unreliable. Therefore, your crawling habits in traffic needs to change when driving a DCT-equipped car. Yes, all the things you’ve read about DCTs being jerky in traffic, are true. This all resulted in a very satisfying driving experience, until you get stuck in traffic.
#Automatic dct transmission manual
Push it to manual mode, and the shifts become even faster, accompanied by the signature ‘farts’ on upshifts. Its 6-speed DCT (or DSG, in VW-lingo) was smooth, fast and returned very decent real-world fuel consumption.
In my time owning the MK6 Golf GTI, I’ve always marvelled at the way it went about its business. Which begs the question, which is the better transmission? This has been a debate that has raged on for some time. Two of the most common types of automatic transmissions today are the dual-clutch transmission (DCT) and torque converter (TC). (function() ) įast forward to today, and self-shifting transmissions have gotten so good, no human input could possibly match its speed and efficiency.
