In case you didn’t know, it’s not really an automatic transmissionby Robert Moore, on
There’s a lot of confusion surrounding dual-clutch transmissions. It’s only to be expected considering it’s a relatively new technology. The truth is, the DCT isn’t really an automatic transmission, and it isn’t really a manual transmission either. It’s a blend between the two. Sure, there’s no clutch pedal but, in fairness, some models don’t have a real “park” position either. As far as BMW’s DCT goes, it’s one of those that doesn’t have a park position, but it doesn’t use a torque converter like traditional automatic transmission either. And, that’s where the confusion comes in. See, BMW’s DCT doesn’t even start rolling right away as an automatic would. It has what the brand refers to as low-speed assist, which means that you tap the gas and it creeps along at a couple of miles per hour. If you come to a stop and let off the gas, it will simply sit there in a neutral-like state. Furthermore, the transmission will automatically shift into “park” when the engine is shut off.
I know, that description doesn’t really help the confusion, does it? Well, lucky for you, BMW has put together a video to help you understand just how well it works. Unfortunately, the man in front of the camera isn’t speaking English, so you’ll have to read subtitles, but that’s okay because it’s certainly worth the read. Check it out and let us know what you think!
