Should the Auto Hold be in D Gear or N Gear?

When using Auto Hold at a red light, if the wait time is long, you should shift to N gear; if the wait time is short, you can remain in D gear. The advantages include fuel savings, reduced strain on the torque converter, smoother transitions when shifting from N to D gear upon starting, and enhanced safety when parking in N gear. Below is an introduction to the gears of an automatic transmission car: 1. L Gear: Low gear, which limits speed. When climbing a slope, shifting to this gear maintains high RPMs at low gear. 2. S Gear: Sport mode, where the transmission can shift freely but with delayed timing, keeping the engine at high RPMs for extended periods, allowing the car to move at low gear and high RPMs for longer durations. 3. D Gear: Drive gear, used for forward movement. 4. N Gear: Neutral gear, used for brief stops. 5. P Gear: Parking gear, used when parking to engage the parking brake and prevent the car from rolling. 6. R Gear: Reverse gear, used for backing up. However, R gear should only be engaged when the vehicle is completely stopped. Shifting into R gear while the car is still moving slowly can cause severe damage to the transmission.
I think keeping it in D gear with auto hold is sufficient, based on my years of driving experience. Once the auto hold function is activated, it automatically brakes the wheels, allowing me to release the foot brake without shifting gears. However, when waiting at a red light or in traffic, if the stop lasts more than half a minute, it's safer to shift to N or P gear, as staying in D gear keeps the transmission connected to the engine, potentially increasing wear or consuming a bit more fuel. Keeping it in D gear for short stops makes it easier to start moving. Remember to check your vehicle's manual for recommendations. In my car, shifting to N gear during peak traffic hours feels smoother and prevents shaking. Also, avoid keeping your foot on the brake all the time; auto hold can make driving more effortless.
