Only thing about turning your car off at a stop light is that it takes more gas to turn it back on then if you had just left it on, so what ever you might think you're saving by doing that...well you aren't. So ya, don't do that

You’re telling me people are driving down hills next to me in neutral ???
Rea Ality
How do these 'never do' things change with a CVT?
gurumyster
One more thing about driving downhill in neutral is the car can accelerate to dangers speed. When you try to stop the car you will encounter few problems.
1. In addition to the speed of the car you also have the weight of the car Pulling forward.This make it extremely difficult to stop the car.
2. Because you’re on a slope car is more prone to slipping during breaking.

It used to be common (?) knowledge that a "brake stand"
could 'balloon' the torque converter......But in those days,
my high school car would put my watch band up on
my elbo when hitting second gear.

If we don't put in Neutral at a stop, when should we put the car in Neutral then?
Jedi Exile

I tested everything regarding car coasting. And here's what i found: I have an automatic sports car and according to my trials and the fuel economy meter, putting the car in N or D makes NO difference in fuel consumption while the car is moving as long as your foot is not touching the gas pedal. But if the car is stationary, idling (stopping) in N will decrease your fuel economy. But putting the car at N and removing your foot from the gas will help the car glide smoother and for longer distances, therefore reducing the need to step on the gas which will make difference in your fuel economy. Consider it a skill to know how to coast the right way. Hope i helped you guys.

I do it to prevent warping my brake rotors. Hot brakes that have one small portion tightly squeezed by the pads will have uneven cooling. This is especially true when coming to a stop quickly or from coming downhill to a red light. In neutral, you don't need to keep squeezing the brake rotors.

Yeah... Just downshift your auto, as long as the automaker is kind enough to allow a peon such as yourself dictate what the transmission does.

Still have no idea how an automatic works.

Common Sense video lmao
Dyab Crook
You don’t say? Turn the car off instead of putting it in Neutral?! 🤔🤔 so not to wear out your transmission you wanna wear out your engine!! Don’t listen to that dude just put it on Parking not Neutral and most definitely do not keep turning on and off cuz the most wear occurs when you start the car since the engine oil will be sitting down

my brother in law never lets the car completely stop when changing from drive to reverse. it drives me nuts

Video takeaway: never ask an engineer a simple question.

Please learn from my mistakes. I went thru half-a-dozen new cars because I thought 'P' was for passing....

Some Saabs automatically go into neutral and freewheel down hills -they automatically return to drive when you touch the accelerator.
Rifky Fahrana

In this video, Sam from http://www.professionalfleet.com in East Lansing Michigan will explain the difference between a transmission flush, transmission service and a transmission drain and fill.
Do you know the difference? How much should you pay for each service?
The price you pay directly effects the service you are receiving.

Dangers of flushing transmission when over 100k miles. We will also cover coolant or radiator flushes as well.

We have found most customers do not know the difference and assume they paid for something that they did not get.
