Sa mga A/T, at the stop light, naka D, N or P

Wear and tear is normal. Trying to stop a car that's engaged to move forward is not. Better put it in N and use your brakes.

Everytime you move it from P to D you incurr huge stress on the engine and transmission mounts and other parts. look at the engine when you move it from P to D and you'll see how the block tries to move in the bay. just use your brake when stopped, keep it in D. the clutch is slipping in liquid so the only wear is the brake pads. put it in N if you won't move for more than 5 mins

mukhang majority nilalagay sa N and naka apak sa brake or engaged yung parking brake

Maybe guys, you should change your habit to put N during stop...

Eto yung ibang reason found in the internet...

Question...
Should you shift an automatic transmission from 'D' to 'N' while waiting at traffic lights?

Answer

No. It shouldn't be necessary and it puts strain on the linkage to shift constantly like that - the whole idea of an automatic transmission is to eliminate the need to shift gears. The transmission has a fluid clutch that is designed to allow for maximum slippage at idle speeds so that the engine very nearly freewheels when stopped.

Source.. Should you shift an automatic transmission from 'D' to 'N' while waiting at traffic lights

Here is the purpose why there is a N in A/T

ANSWER.. That N is where it is also because Uncle Sam said it would be there. If you find a 1950's car with an automatic (and I have seen this in a '57 chevy) instead of P R N D L you will see P N R D L. There were a lot of accidents caused by persons who thought they were in drive but took off backwards while looking forwards or visa versa to help prevent this the Federal Transportation folks mandated no automatic transmission would have drive and reverse side by side in the shift pattern. The folks in Washington do come with a good idea every now and then.

Common Myths Among Young Drivers - Cars.com

Myth No. 5: It's best to shift an automatic transmission into Neutral at red lights. This myth stems from the idea that keeping the transmission in Drive while stepping on the brake wastes fuel and causes unnecessary wear on the driveline. In fact, actual engine wear and fuel loss are minimal.

Regularly shifting from Neutral and back into Drive when the light turns green, then immediately stepping on the gas, can wear — albeit slightly — on the transmission, driveline and engine mounts. Ultimately, these stoplight antics probably won't amount to any measurable harm or good; they're likely just a habit by folks who need to keep their hand busy with the gear selector. Our advice? Get a stick shift.

Ang praktis ko po ay: (1) kung mahigit sa 1minuto o higit pa, aking inilalagay sa neutral at gamitin ko ang hand brake; (2) kung walang 1minuto naka tapak lang ako sa preno. Ang mga nasabing oras ang mga estima lamang at ito ay aking ginawa sa dahilan lang na mas convenient ako. Hindi ko din alam kung ito ay meron masamang epekto sa matagalang pag gamit.

This is still my practice & my reply,

" Quite a number of drivers, particularly the ones who picked up bad driving habits from other drivers who didn't know any better, often practice improper driving by not shifting to neutral when the car is not moving. While I would like to tell you that there is a good reason (under normal circumstances) for keeping it in D and stepping on the brakes at a stop, I can't.**It's mostly born out of laziness and improper training.*

As you have correctly surmised, the engine does consume more fuel and you do wear down your brake-system components more when you leave your transmission in D or Drive while the traffic light is red or when you’re idling and waiting.

With automatic transmissions, the engine is energizing or driving the transmission to move in the direction of the gear you've selected--forward or reverse.**When you keep it in gear*, you are telling your vehicle to move;**when you're on the brakes*, you're preventing motion. You're unnecessarily and slowly raising your automatic transmission fluid, wearing out your transmission clutches, and consuming more fuel because you're on the brakes to keep the car from inching forward. You're also unnecessarily wearing down and heating up your brake pads. By simply shifting to N or neutral there would be no need to apply the brakes with the amount of force required to resist forward motion.

It depends on the automatic. DCTs automatically shift themselves into neutral at the stoplight so you don't have to. But with automatic transmissions, it's best to keep it in neutral to prevent heat build up and eventual shearing of the transmission fluid when stopped in traffic.

To prevent excess wear on the clutch packs when doing this, simply wait after you shift it into "D" before stepping on the gas. Simple, really.

P or D .. kotse nyo naman yan. What ever lights your fire guys.

**Horsepower** · October 29th, 2012 04:49 PM

N. It's simple, D tells your car to engage forward gears. Then you stop that by braking. Something, somewhere will fail there.

**1D4LV** · October 29th, 2012 04:57 PM

driving an automatic is very simple...

Starting : Put it in P
Moving: Press the brake, put it into D, remove your foot from the brake, press accelerator.
Stopping: After a full stop, put into N.

In a traffic light, much better if you can put it in N, so the transmission is disengaged. it will also lessen the wear and tear of the brakes.
