How Does One use an Automatic Gearbox? - boxer99
Hi,

As you all probably know my FIL has bought a Rover 825 sterling Auto.
As this is his first ever auto, and as I have never had an Auto I have been asked by him to ask how does one drive an Automatic car properly.

Obviously N is for Neutral

R for reverse
D for Drive
1 and 2???? I dont know what they are for!

Questions is on a motorway or speeds above say 60mph which gear does noe use.
At traffic lights do you leave the car in D with the foot on the brake or put it into neutral.
Whats 1 and 2 for.
What gear would you use for a traffic light drag race (not that he would ever do that)
Any other suggestions of how to drive practically using an autobox?

regards

Gears 1 & 2 are generally used for engine braking - if he decides this is what he wants to do rather than letting the brakes do all the work. Volumes have been written on the pro's and con's of engine braking if you do a forum search.

Sitting in 'D' with the foot on the brake is inconsiderate for drivers behind as they get dazzled by the high intensity brake lights.

As well as warping the brake disks due to the expansion caused by hot pads pressing against the disks.

1 and 2 are 'holds' for the lower gears. You wd use them e.g. when descending a very steep hill to provide some engine braking or when climbing a twisty road, either to maintain speed or to stop the auto 'hunting' between gears. In fact there is seldom any real need for the intermediate holds. Use D, and get used to the way the thing behaves so that you feather the throttle to prevent unnecessary changes and minimise fuel consumption. Flooring the throttle in D should result in one or two downchanges depending on your speed at the time. Frequent use of kickdown will cost you plenty petrol.

usually you start it up in park, stick it in drive (or reverse if you wanna go backwards) and thats it. and thats all you do

Loads of people will come on here and say

ah you should be in Neutral at traffic lights, you can if you want or you can hold it on the handbrake

1&2 are for holding lower gears higher int he rev range

1 - if you start in 1st it will never go above 1st. It wont drop down into 1st if you select the lever there unless its going slow enough to do so

same applies for 2 (except its second gear)


You also have kick down. Push the throttle all the way to the floor and it should kick down one gear if possible for faster acceleration.

Oh word of warning

Dont stick it in park while the car is moving. Expensive bits fly out the gearbox if you do.

so if you wanted to build up some speed t0o say 80 and say your already travelling at 50 you would floor the throttle....wouuld this be the quickest way to build up speed?
Also for normal city driving stop start etc whats the mose economical way to se the box?
Stick it in d and drive?
what should one do at traffix lights?
How Does One use an Automatic Gearbox? - Xileno {P}
Flooring the throttle will increase fuel consumption and is mechanically unsympathetic at this speed. At 50mph I would just press the pedal gently down a bit more.

Town driving - I would just stick it in 'D' and let the car do the work. Is that not the main point of an auto gear box?

At traffic lights I would put it in 'N' and the handbrake on.

And I use the right foot on the accelerator and left for the brake. Cue another long tired old thread.
How Does One use an Automatic Gearbox? - Lud
Stick it in D and drive. If stopped for long at lights use neutral (leaving it in D will heat the box and degrade the fluid unnecessarily). My own experience with autos is that when you put the lever back in D there is often a clonk when the drive takes up, after a short delay. If you move the lever from N or P to D and don't wait for the clonk before touching the throttle, you will embarrass yourself and perhaps do damage as the drive takes up violently. A bit of practice will teach you the correct rhythms for the car.

Slight topic drift, perhaps worthy of its own thread, but why oh why do autobox control levers have to occupy the same floor-mounted position as a proper gear lever? They used to be column-mounted, with an indicator before the driver's eyes, and those were much easier to work and more convenient, as well as not having a damn great umbrella-handle stuck in the middle of the car and an indicator absurdly far from the driver5's eyeline.

Can anyone explain this apparently perverse practice by car manufacturers? Does it make Slobmobile drivers feel sporting?

Dunno, guess because you've already got your indicators, wipers, cruise and stereo controls coming from the column. I'm always catching my knees on one stalk or other as it is.

Always room for another stalk BBD, or these days a row of buttons or a thing sticking out of the facia a la DS...

But what are your knees doing at that level in the car? I know driving's fun but it isn't meant to be a literal knees-up.

Can't get comfy Lud. I'm tall but I can't push the seat back because the boy sits behind me. I like the seats high as poss to support my thighs and the two lower stalks just hang low. It's irritating to keep accidently changing radio stations but it's thoroughy disconcerting to hit the "resume cruise" as you're taking a tight bend. For me, just getting in the car is like unfolding a big wooden deck chair.

Our Honda Shuttle has a colum shift, and it is a UK spec car, makes life easy for swmbo to get access the the kiddies in the back - much better then having it on the floor in the middle.

It would be the quickest way to build up speed.

Just drive like you drive an manual car but don't change gear. If you want to accelerate a bit, then press the pedal a bit. If you want to accelerate a lot, then press the pedal a lot.

Don't forget that you don't have much in the way of engine braking, and that's about it.

Much nonsense is spoken about how the guy behind will get dazzled - I don't think I've ever been dazzled by brake lights, but perhaps I just have very butch eyes - so I wouldn't worry about it.

Drive around town, use the handbrake when you would use the handbrake on a manual, use the foot brake when you woudl use the footbrake on a manual, but don't forget if you have no brakes applied yet the car is in drive, it will usually creep forward.

As far as I can think quickly, good practice in a manual and good practice in an auto is the same thing. Ditto bad practice.

Brake with left foot
How Does One use an Automatic Gearbox? - Nsar
Oh and don't forget the first time you drive it, it's the law that you have to forget that it's an automatic and when you first to come to brake, you boot the pedal with your left foot, more or less lifting the back axle off the ground.

Well that's what I did anyway, a long time ago in my boss' very expensive BMW

Yes I did that too in a hire car in Las Vegas. A Ford Taunus 3.2 with column change automatic. The hire bloke said, "do you know how to drive one of these". "Yeah of course mate, no sweat." was my reply. Figured out how to get it in drive with the bloke watching, rolled to the kerb line, busy traffic on the "Strip", then hit the brake with a left foot that was used to pressing a heavy clutch. Not cool!

Very embarrassing indeed. I did it in an immaculate NSU RO80 which not only had a twin-rotor Wankel engine but a 3-speed box with an electric clutch worked by hand pressure on the gear lever (always a silly and annoying idea I thought). First junction, left foot came down on 'clutch' heavily as usual. Oh dear. The car's owner, an African, was polite but far from amused.

In my Plymouth I once put the car in Park (it had a separate lever for the purpose, buttons for the other gears) when it was moving, fortunately quite slowly. There was a loud clang as the transmission lock applied itself, and a chirp from the back tyres, but fortunately US ruggedness meant no damage. Never did it again though.

Mercedes put the pedal for the "hand"brake where the clutch would normally be on their autos. I've moaned about this before. Insane. I had to sit on my own left foot to stop myself from stomping on the "hand"brake and locking up the rears.

IIRC this car has an LPG conversion doesn't it? Be interesting to see how the autobox handles the (presumably?) different characteristics of the engine when running on LPG.

I dont think lpg should change the driving characteristics of the car? am i right?

Form my own web surfing when considering LPG then economy drops by around 20% and performance drops 'a fair bit' - but that isn't from personal experience.

As you would drive any other car - with more care and attention.
how about in snow?


Don't know about the Stering, but my Galant has a "Hold" button. Pressing this stops the car from going any lower than the current "highest" setting (1, 2, 3 or D(4)) which means if you press "Hold" and select "2" it'll hold the car in second to stop you wheelspinning. Effectively the gearbox becomes a semi-automatic at this point. Not all autos have this though - but I'd imagine most will have some sort of snow/ice setting.

I've always brake in an automatic using my right foot with one exception, on the rare occasions when using a Toyota RAV4 for off-roading.

In fact it's the only way you can go around a 4x4 course in a RAV4, which doesn't have a very low ratio gearbox.

Yes: not all the time, but quite often.

When I started doing it, I several times found myself inadvertently winding the two pedals against each other, but that doesn't happen any more now that I am more practised. So I use the left foot when in heavy traffic and may need fast response, but which foot I use the open road depends largely on whether I want to rest my left leg: I now find that my reactions are fine either way.

How Does One use an Automatic Gearbox? - Lud
I agree TVM. Left foot braking takes real practice, and is only necessary when you are pressing on in an ambitious way. Can be damn dangerous in traffic until the skills are built in. Use the right foot on both pedals, whatever HJ may say, until you have the technique properly internalised.
How Does One use an Automatic Gearbox? - boxer99
I think FIL is using right foot for brake and accelarator.


if a car is left in drive but no pedals pressed at all will the car move forward on its own accord?
How Does One use an Automatic Gearbox? - AngryJonny

Downhill, yes

Uphill, probably not, but it shouldn't roll back (if it does get your gearbox seen to)

On the level, it will slowly roll forwards, yes

How Does One use an Automatic Gearbox? - Vin {P}
I may have missed an answer here, but ref acceleration, if you put your foot to the floor, the 'box will change down to the gear giving maximum acceleration at your current roadspeed. It's known as "kickdown" and is very effective for overtaking, as it'll always put you in the right gear.

Though as was mentioned above, the simplest way to understand it is that you hit the right hand pedal to go and the left hand one to stop. The harder you hit the right hand pedal, the faster it will accelerate.

Most autos have creep - This is when in D or R, the car moves forward slowly on its own. Therefore as you release footbrake the car moves - So you kind of using the footbrake like a clutch. This is useful for parking as it allows you to maneoveur with the footbrake. It is also very nice for traffic jams. On most hills the creep will be enougth to stop you rolling back. On very steep hills use accelerator and possibly handbrake.

Ive always used my right foot for both pedals and would recommend that. Therefore dont use your left foot at all. That is what you are used to with manual. If you do use your left foot, you will find it very unfamilar and it will take you a while to get used to it. Using your right foot for both pedals makes it easier switching between manual and auto cars.

Use D the majority of the time. You can use 1 and 2 on steep hills for engine braking, but you dont have to. Use kickdown for quick acceration e.g when overtaking.

Your car may have the following:

Sport mode - holds each gear for longer, making it faster/sportier

Snow mode - moves the car off in higher gear and keeps it in high gears.

I may have mised this above but even if so it's worth saying again.

If someone is new to an automnatic, they should always, ALWAYS have their foot on the brake when shifting from P or N to D or R. Avoids unintenional surge forwards or backwards into trees, bollards or parked cars.

Left-foot braking is fine if you're used to it, but again if new to automatics stick to what you know and brake with right foot only. Ditto if you regularly also drive a manual, as I do (SWMBO doesn't like automatics so we have one of each).
How Does One use an Automatic Gearbox? - Pete M
One very small point. Above, a number of posters have mentioned kickdown, as in pressing the accelerator until the box changes down a gear. I do believe that 'kickdown' is something different. When the accelerator is pressed fully down in normal driving, the car will use the auto box as described, changing down as required for maximum acceleration. All my automatic cars have had an extra position beyond 'full down'. You have to press fairly hard to feel it but there should be an extra 'jump' as the pedal goes further. This position mechanically or (usually) electrically forces the gearbox to immediately change down a gear for extra power. A lot of automatic drivers don't know this is there, but if you need power in an emergency, this is how to get it.
The other tip I have is to tuck your left leg away behind your right leg. It feels a little uncomfortable, but it prevents the unintended stab at the absent clutch pedal hitting the brake as mentioned above.
Some posters have advised putting the gearbox into neutral at lights. I have been told that the action of putting the car in and out of drive so often does more damage than sitting at the lights idling in drive. The amount of pressure on gearbox components in that situation is extremely low, and they are designed to cope with it. As mentioned above, in the USA, everyone just leaves it in drive, and they probably know more about automatics than anyone else. You could just apply the handbrake, leaving the car in drive, with the footbrake off, if the thought of your bright lights irritating the driver behind you is worrisome.

I have both a manual and auto. All you really need is P, R and D in an auto.

Automatic gear boxes have been around for decades and consitute the vast majority in the worlds largest car market. There is really nothing special to do.

Every auto car I've ever owned has come with a handbook that gives full instructions on how to drive it - and I still read them, after 25 years, just in case there's a quirk I didn't know about.
I guess, at 1500 notes, the Rover must still have one tucked away somewhere...
And - although I hesitate to get into this debate yet again and no matter what HJ thinks - I always drive right foot only. About 400,000 miles doing it that way must mean something.
How Does One use an Automatic Gearbox? - Mookfish
My Renault auto has a sizable footrest for your left foot, after driving manuals I find I keep pushing down on that, saves alot of unintend heavy breaking.

Also there is another use for the 2 position, if third gear stops working!
