Should release brake and let Auto car stay on slope?
-
Anyone able to advice if there's any harm to release brakes and just let an Auto car "balance" itself on a slope (not steep enough for the car to roll back) while waiting for traffic light to turn green? Or should the N gear be engaged and then press the brakes to avoid roll back?

By engaging the neutral shift it will cause premature wear and tear on the gear box. Always engage in drive mode and depress your brakes.

ditto

Using the brake on the slope ensures that the car won't slide back and hit the car bahind you... letting it balance is kinda risky.. esp if something happens and the car can't balance... don't need to shift to N either... just leave it at D and step on the brake...

what happen waiting at traffic light when red.....do we need to change to neutral or Park, will the gearbox wear for the change??
thanks -
it seems many people dont like to step on the brakes?.. no need to change any gears just step on the brakes.. that is reason you buy an auto car right..

didn't know abt that...thanks for the infoOriginally posted by Praetorian111:By engaging the neutral shift it will cause premature wear and tear on the gear box. Always engage in drive mode and depress your brakes. -

wah lau the car i drive in reality is not la....wtf...its just an automatic wagon...Originally posted by bismarck:takumi driving AE86 auto ? -
Out of curiousity, does that make Neutral redundant??Originally posted by Praetorian111:By engaging the neutral shift it will cause premature wear and tear on the gear box. Always engage in drive mode and depress your brakes.

is there any proof or write-up about using neutral frequently causing wear n tear on the gear box? i had been taught to always put to neutral during red light so as not to overwork the engine ie, the car will not try to push forward. otherwise, wat exactly is the neutral gear for?Originally posted by Praetorian111:By engaging the neutral shift it will cause premature wear and tear on the gear box.

besides, sometimes your car can amaze you. I left the Merc E200 Kompressor on a really steep slope. Perhaps 15 to 20 degree slope. with D engaged, even though im not on the gas, the car managed to roll UP the slope! of course we were at a dead crawl, but most cars i know would be nicely balanced without moving forward or backwards. this one definately need to hold brakes. no wonder brake wear n tear a bit high.Originally posted by LH83:Using the brake on the slope ensures that the car won't slide back and hit the car bahind you... letting it balance is kinda risky.. esp if something happens and the car can't balance... don't need to shift to N either... just leave it at D and step on the brake... -
is there any proof or write up that states u should always put ur transmission into neutral so as not to overwork the engine?Originally posted by Newdriver:is there any proof or write-up about using neutral frequently causing wear n tear on the gear box? i had been taught to always put to neutral during red light so as not to overwork the engine ie, the car will not try to push forward. otherwise, wat exactly is the neutral gear for?
there are merits to both practices i presume.
constant engaging and disengaging between "D" and "N" causes the torque convertor additional stress because of the fact that it runs on a fluid coupling effect. ie; the harder u step on the throttle, the more fluid gets forced into it and the more forward motion it generates.
at idle, the amount of thrust generated by the torque convertor as a result of the engine's speed is minimal but optimal for move off. if u engage "N" at this point, the pressure build up in the torque convertor is relieved. when its time to move off, and u reengage "D", the pressure will take time to build up to turn the convertor again to generate the same forward force.
now, u dun need a phd to understand that this constant changes in pressure using the fluid coupling effect and the effective fluctuations in the rotational speeds of the mechanical parts will result in pre mature wear and tear.
likewise, one can argue that the engine will be "stressed" by constantly working to provide this pressure build up to keep the torque convertor under such conditions. but IMO, if its anything thats the weaker link here, it's gotta be the automatic gearbox.
i've seen more breakdowns in auto gearboxes but hardly in any of the engines running them. which goes to show how well informed some drivers of automatic transmission are in this aspect of care for their gearboxes.
what is "N" for exactly? i can only think of one logical question to ask in answer to that. try pushing ur car in "P" when it breaks down. -
New driver can I ask you another for manual cars.
When you stop the car do you put to neutral or engage in first gear? And why?
As for the explaination for auto, tailslide is quite right in his explaination. Wear of auto gear box is quite costly to replace and therefore keep this advise in mind.

To tell u the truth, i only drive manual cars when i was taking my driving lessons betwn june to dec last year. my instructor told me never to engage neutral whilst at traffic junction but of course to engage to neutral at the end of the lesson. so i never fully understand the difference until now. but i always see taxi drivers putting to neutral during jam and red light. why?Originally posted by Praetorian111:New driver can I ask you another for manual cars.

actually i prefer to stay put at D gear during jam and red light, firstly becos i'm afraid tat i may forget to change fm N to D and hold up traffic and secondly, it is so cumbersome having to move the gear stick. since my car is auto, why not just stick to D all the way and let it do the work itself? however, i'm very careful about 1 thing though. being a new driver on the roads, i always cover my foot brake all the time.
tailslide and prae11, thanks for yr advice. i just bought my precious new car so dun wish to damage the gear box.
