AT stopping distance?

[pup2]

Mas mahaba nga ba ang stopping distance ng AT? Would putting it into N BEFORE stopping help? Would it even be advisable?

[Alpha_One]

Putting the tranny into N before stopping would probably increase stopping distance. Letting go of the accelerator already induces engine braking, while this isn't exactly as instantaneous as on a manual, there is definitely such an effect on A/T cars. Disconnecting the engine from the tranny (putting it into N) means you lose the engine braking. It may also be dangerous.

You're not supposed to shift in and out of Neutral with the vehicle in motion.

[Lucius]

Stop, brake tska lang mag-N hehehe

[theveed]

brakes stop the car, not tranny or engine.

[alwayz_yummy]

tama.. preno mo lang, pag huminto na tsaka lang ka mag N..

ang difference lang ng a/t, kung hayaan mo, di ka hihito!kaya preno mo lang till it stops...and di mo feel ang engine brake kasi bahala na ang a/t mag timpla...

kaya, logically, walang maling "timpla sa a/t", therefore, di ka mamatayan ng makina whe you go from still->go! except kia ng mom ko, makamali lang ng apak, patay makina...

[dennis powell]

mas okey pang nakahinto yung kotse na nakdrive yung shifter nya kesa ishift mo sya sa neutral habang tumatakbo yung kotse mo.masyadong delikado.

In braking, weight does come into play, and a M/T tranny is not as heavy as a A/T tranny.

[danesjr]

technically yes. because of the fact that an AT is heavier. so two cars with the same specs but differs only in the transmission used, it is understandable that the AT car would take more distance before coming to a halt than the MT car. inertia nga ba tawag dun? pero sa tingin ko negligible yung difference.
don't place it in neutral, lalo ka mahihirapan huminto. as they say, engine break helps slow you down.

[IMm29]

yup, you'll probably end up braking longer with an AT. but don't put the shifter in Neutral when braking. that's not safe. leave it in D, and let the engine and tranny haul your ride down for you. just leave a little more allowance for braking if you're used to an MT car.

[theveed]

unless you're doing an emergency brake or high-speed braking scenario, i sincerely doubt you'll notice a difference without getting to technical about it..

[rion]

yes, mas mahaba ang stopping distance when you go N. (specialy with a worning out tranny vehicles[too early downshifts]) but if you are thinking of saving fuel by doing that... not effective...I used to do that. not to save fuel, but just an "N" addiction of mine. even now I do it sometimes... naging BAD habbit ko na kasi eh...

[pup2]

Ah. Thanks for the input guys. Actually, naisip ko lang yun kasi while naka-drive na ako ng AT, mas sanay ako sa MT before. Eh style ko nun pag pa slow down na ninu-neutral ko na before full stop. Bale I just coast along. Obviously, hindi naman siya emergency situation or anything pero parang feeling ko mas malakas ang stopping power ko at mas matipid sa gas.

I was just wondering if this could be used sa AT. I've never had this problem with AT's before kasi parang ambagal na nga ng AT's sa akin eh. Pero yung FXT ko kasi parang ayaw pumara sa lakas ng batak eh (new pa siya). Would you suggest a brake upgrade or something?

[rion]

your FXT is A/T right?

I don't think upgrading brakes is the answer, I suggest coast along slowly before full stop nalang. it will even save you fuel. I think it's the habbit you have in M/T, the "avoid lower gears" thingy. so you go fast or in high gears in M/T and you just slow down when the full stop is very near na. while in A/T, you go slower and just coast along when the full stop is still NOT so near pa...

M/T is like a pushing boat, while A/T is like pushing wave. the boat is faster than the wave. to stop the boat is just to stop pushing, while the waves, even you block it, there are still bit's of waves left pushing...

that waves is really your ATF.

I learned a lot from this site

Anyway, instead of starting another thread, just want to ask regarding emergency stopping a vehicle with AT if it looses its brakes? (specially running at highways or EX way)

Safety First! yes,, it is.. but what if that happen? AFAIK, MT can be slowed by the lower gears? How about for AT? Can one shift to P for emergency stopping of the car? (to save life.....at least)

Thanks in advance!

Shifting to P while driving will take out the parking pawl and eventually ruin your transmission. That's why you can't shift to P from D without pressing the button, failsafe mechanism yan.

Think of it this way, the brakes and transmission do not directly increase the grip or the stopping force. What actually does that is your tires. If your tires are at its max decelerating rate, shifting to a lower gear (AT or MT) will not help. So to answer your question if you lose your brakes, put on the hazards, let faster vehicles pass you and wait for a good, long opening, then shift to the next lower gear (when driving an AT make sure you know the gear's speed limits - check your owner's manuals) until you can shift another gear down or until you get to the shoulder safely. Shift to P or N and activate the handbrake, then get out of the vehicle and stay as far away from it and call for help, some reckless drivers might plow into you (passing on the shoulder, etc).

ABS increases stopping distance too. The key is to mash the brakes when using ABS, and use the steering wheel to steer away and avoid a collision.

Shifting to P while in motion will almost guarantee ruining your transmission.

When you lose your brakes, the first option of course is the emergency or parking brake. If that's also gone, you can force an A/T to downshift by shifting to 2 or L (or equivalent). There are maximum speed ranges for each gear, so you have to know them and keep in mind NOT to downshift if you're going faster than the limit. Of course, if there's no other way, go for it. A busted transmission is still better than losing yours or other people's lives. ;)

[mbeige]

Using the E-brake alone to stop the car also might force the car into a spin, especially if you had to avoid something. I'd use it as a last resort.

[pup2]

Hmm...good idea. I'll try coasting by just lifting the gas pedal fully.

Yes, I believe engine braking by shifting to lower D gears would be better than shifting to P -- pag nawala na nga naman tranny mo, wala ka ng engine brake.

[pentium9]

Thanks for the response guys!

I think I would go to forcing to lower gears instead...(just in case!) . I'll try to keep in mind all of your advise.

A part of defensive driving is being prepared and have the presence of mind in times of emergency.
