My husband kicks it into neutral a couple hundred metres from the intersection and rolls to where the car needs to stop, then applies the brake. I gear down as I approach the intersection and then apply the clutch and brake to a stop, gearing down so I wait out the light in first gear. His argument: Neutral saves gas and grinding of gears plus you don't have to keep your foot on the clutch. My argument: Keeping the car always in gear means if I need to quickly manoeuvre like if I'm about to be rear-ended , I'm ready to go.
So, who's right? If you and your husband are giving each other the gears over the right way to stop in a standard, you're not alone. If you shift into neutral before the light and coast, it increases wear and tear to your brakes.
Gobeil said the habit also "results in a lot of unnecessary clutching in traffic — so, a little more wear on the clutch mechanism — and slightly less control" on the road. While the Highway Traffic Act doesn't specify how you drive a stick, your husband's technique wouldn't pass the Ontario road test, one instructor saod.
Shifting sequentially down to first. Another reason to not put the vehicle into neutral while coasting is that it takes away some of your control. Doing this can result in premature wear and failure of components inside the transmission.
So which amount do you prefer paying? Inside an automatic transmission are clutch packs and clutch bands that use friction to move certain parts when shifting. Revving the engine and then immediately putting the transmission into drive causes those clutch packs and clutch bands to prematurely wear out and what happens over time is that the clutches lose their ability to hold friction and the automatic transmission begins to slip while in gear.
The clutches themselves are not expensive pieces but it is expensive to take an automatic transmission out of a vehicle and then tear it down to reach the clutches that require replacing. If the vehicle is still moving, however, it is very easy to break that notch inside the transmission. Previous Post Next Post. I'm betting it's a lot longer. Putting it in neutral will somewhat reduce your available braking force, as you're removing engine braking from things.
No power is going to go from the "idling" engine to the wheels in anything relatively modern. Basically every fuel injected engine since the 80s implements deceleration fuel cutoff DFCO , which stops injecting fuel if the wheels are in motion and your foot is off the gas. As a result, the engine is only kept spinning by pulling energy in backwards, somewhat braking the vehicle.
The benefit is that by removing the engine from the equation, you get much more controllable and predictable braking, which is important in extreme conditions, like stopping on ice, especially if one doesn't have anti-lock brakes. Torque converters "Lock-Up" when the car is being Driven by the engine. NOT upon deceleration. When the brake pedal is depressed enough to cause the "Brake-Lights" to illuminate, the torque converter is taken OUT of the equation. Also, if operating properly, the torque converter will, in most applications, ONLY "Lock-Up" when the transmission is in Top Gear, and you are no longer accelerating, or barely accelerating when your vehicle speed is around mph, and the reduced "Load" on the drivetrain, determined by measuring engine vacuum, throttle position, current gear, and vehicle speed , then the "Lock-up" occurs.
If you continue accelerating moderately to hard, you may find that you're up to mph or so, and the torque converter still will not have "Locked-Up". Engine braking will automatically take place and greatly improve your stability during the stopping process. I won't use the term "Overdrive" because there"s a too universal mis-understanding as to just what overdrive actually is.
As always, there's exceptions.. My old van was equipped with a 4 spd automatic, but the torque converter would frequently "Lock-up" while in 3rd. I had the wrong size tires on it.
If you can hit the breaks hard and quick enough to lock the wheels or activate the ABS with no discernible delay then the engine and transmission is no issue.
I have been shifting cars into neutral and braking, in neutral for 10 years now. Braking in neutral does provide better braking than in gear. In gear, you car is being pushed by your transmission. So as you brake you are fighting with the transmission to stop the car. I guarantee you that I can stop my car which does not have ABS brakes, shorter than someone with ABS brakes all by putting my car in neutral and theirs in drive. This may not be seen with a soft braking, this will be noticed in hard braking.
I also noticed the tires don't not screech in neutral with a hard braking. I think it is because it activates the rear brakes so instead of the front two locking up now there is 4 wheels braking. Also keep in mind that in neutral, your engine idle goes down, as a result vacuum pressure goes up. Since car brakes function on vacuum pressure the higher the vacuum pressure the better the brakes function. The brake fluid only gets fluid to the brake caliper, it requires Vacuum to bring the fluid back to the Master Cylinder.
