Should I shift to N when stopping with a 7-speed dual-clutch transmission?

It is optional to shift to N when stopping with a 7-speed dual-clutch transmission. This is because the dual-clutch transmission disengages the clutch when the brake pedal is pressed during a stop, preventing the engine's power from being transmitted to the transmission. As a result, the car cannot move forward, so shifting to N or not shifting to N are both acceptable. Here is some related information: Dual-clutch transmission: A dual-clutch transmission is a relatively simple automatic transmission that essentially adds an extra clutch and a set of shift control mechanisms compared to a manual transmission. One clutch in the dual-clutch transmission controls the odd-numbered gears, while the other controls the even-numbered gears. Dual-clutch transmissions offer fast shifting speeds and relatively high transmission efficiency. Classification: There are two types of dual-clutch transmissions, dry and wet. The clutch plates in a dry dual-clutch transmission are not immersed in transmission fluid, whereas those in a wet dual-clutch transmission are immersed in transmission fluid.
I've been driving a 7-speed dual-clutch car for quite some time now. When waiting briefly at a red light or similar short stops, I always shift to Neutral (N). This prevents the car from constantly shaking, eases the transmission, and avoids partial clutch engagement, ultimately extending the vehicle's lifespan. For stops lasting just a few seconds, staying in Drive (D) is acceptable with no major issues, but for pauses exceeding half a minute, shifting to Neutral is more prudent. On inclines, I'm extra cautious—first shifting to Neutral before Park (P), then engaging the handbrake to prevent rolling. Adopting this habit has made my drives smoother and saved me repair costs. Remember, don't skip shifting to Neutral—it's a simple step that protects your car, and the long-term benefits are substantial. Short stops: Neutral. Long stops: Park. It's a reliable approach.
I have some knowledge about the 7-speed dual-clutch transmission. It has two clutches inside that work alternately. If you keep it in D gear when stopped, the clutch remains in a semi-engaged state, which can easily lead to overheating and wear. I always shift to N gear to disconnect, allowing the transmission to rest and reducing the likelihood of issues. For brief stops like traffic jams or waiting at lights, shifting to N gear and applying the brake is sufficient—it's worry-free and safe. For long stops, you must shift to P gear and engage the handbrake. Technically, dual-clutch transmissions are more prone to overheating than traditional automatic transmissions, so shifting to N gear can reduce the chance of failure. I always check this habit before driving, and sticking to it keeps my car in perfect condition. Simply put, remember to shift to N gear to protect the core components.
