Should You Shift to Neutral at a Red Light with an Automatic Transmission?

[DiCalvin]

When waiting at a red light with an automatic transmission car, it is recommended to shift to neutral. If the wait is longer, you can also engage the handbrake. Here are the relevant details: 1. In situations like waiting at traffic lights, traffic jams, or picking up passengers where temporary parking is required, many drivers are accustomed to the "D gear + brake pedal" method. However, this habit is not ideal. If the parking time is short (e.g., within 20 seconds), the gear lever can remain in D position while only pressing the brake pedal. 2. For slightly longer waits, it is best to use "N gear + handbrake" to reduce driver fatigue and prevent the automatic transmission fluid from overheating, which could affect its quality.

When driving an automatic transmission car, I usually don’t shift to neutral at red lights. Modern automatic transmissions are well-designed, and keeping it in D (Drive) while braking won’t harm the transmission because the oil pump maintains lubrication and pressure inside. Shifting to neutral and then back to D later might increase gear shock, leading to more wear over time. Some claim that shifting to neutral saves a bit of fuel, but the actual savings are minimal—just a few cents—and not worth the hassle. I’ve tried shifting to neutral in highway traffic jams and felt little fuel savings, while the slower restart affected smooth driving. My suggestion is to simply stay in D and brake—it’s easier and safer. If fuel economy is a concern, check your car’s maintenance or optimize driving habits, like using the AC less.

Having driven automatic transmission cars for over a decade, I always firmly hold the brake in D gear at red lights without bothering to shift to neutral. This is primarily for driving safety: I can immediately step on the accelerator when the light turns green, avoiding any delay from gear shifting; if left in neutral, forgetting to shift back or slight vehicle coasting could lead to minor accidents. In situations like sudden braking I've encountered, staying in D gear allows quicker reaction to avoid the car ahead. Regarding fuel consumption, modern engine technology has made neutral gear's fuel-saving effect negligible, so it's not a priority. Daily driving emphasizes convenience and peace of mind - shifting to neutral is an unnecessary step. It's better to focus on road conditions while reminding regular checks of brakes and tire pressure to prevent issues.

As an environmentally conscious driver, I believe shifting to neutral at red lights doesn't make much sense. Modern automatic transmission vehicles already have very low fuel consumption when braking in D gear. Shifting to neutral might save a tiny bit of fuel but it's negligible, and could potentially increase exhaust emissions, making it less eco-friendly. I focus more on good driving habits like smooth acceleration and deceleration to save fuel. Shifting to neutral poses higher wear risks to the transmission and isn't a sustainable practice; modern cars even have start-stop systems that automatically shut off the engine for better fuel efficiency. Simply staying in D gear is the most reliable approach.

I've been driving my kids to and from school for ten years, always stepping on the brake and staying in D gear at red lights, never shifting to neutral. I find this simple and convenient, as shifting to neutral seems cumbersome and time-consuming, especially when the kids are noisy and I'm in a hurry to drive off. In the old car era, shifting to neutral might have saved fuel, but my car automatically optimizes fuel consumption, so I don't notice any difference. On the contrary, shifting back from neutral often causes jerking, affecting driving smoothness. Experience tells me that keeping things as they are is hassle-free and reassuring, and can also reduce wear and prolong the life of car parts. Regular brake pad checks are sufficient for daily maintenance.

For new automatic transmission cars, I recommend not shifting to neutral at red lights. Many vehicles now come with start-stop functionality, where the engine automatically shuts off when stopped at a red light without requiring manual gear intervention. Shifting to neutral is redundant and may interfere with the system operation. Transmission technology has advanced - maintaining D gear while braking achieves pressure balance without causing additional wear. Modern vehicles manage fuel efficiency effectively, so why complicate things? Personally driving a start-stop equipped car, the throttle responds smoothly when the light turns green - shifting to neutral is an outdated habit. I suggest focusing on keeping up with new trends like paying attention to cigarette lighter or navigation details instead.
