In mine... short 1 or 2 miles trips... 28mpg. Around town/sub-urban ... between 32 - 35 mpg. Motorways at about 75mph ... I get about 46mpg. These were measured miles per fill-up, but tied in fairly well in what the trip computer wanted to say

I get 31MPG commuting 14miles through urban streets.
The meter in the dash says 36.7, it also thinks I drive 15.3 miles to work.

Not as good as I'd hoped, not as bad as the Range Rover though

low to mid 30's around town a bit more with the overdrive turned off 45-55 on a longer motorway run
if you have a heavy right foot you can get it down to 26 mpg around town

If you use the gear box for slowing down this improves the economy but not much.All Depends on how you drive, or Your Driving Style!

changing down manually with an auto box will A. burn the fluid and B.kill brake bands and/or kill the solenoids

it will all end in tears

Hi Flash again we meet on this one.If you use the gearbox on an auto instead of just "D" all the time it allows the engine to work to its full optentail and not always in kick down, You will notice that in kick down in"D" the engine doesnt build up to its max revs before changing gears, however if you car is well cared for and looked after the gearbix will out last the engine.
The Gearboxes in the Nissans are stepped unlike some of the cvt ones (constantly variable transmission) originally made famous by the Daf in the early 70's.
I have been driving both Autos and Manulas for a long time and have driven every type of car you can imagine, if you treat your car like you do your children/plants itll return with good performance.
Lastly how can you kill the brake pads >:? i guess you mean the torque convertor? if you change down to 2nd at approx 40mph theres no need to use the brakes all the time, plus theres the over drive too, when you on the motorway especially when over taking its a good way to change down so to speak.
You would only kill the solenoids if you changed from D to 2nd at a higher spead normally above 60mph (indicated by the speedo)
I agree the realy hard driving without maintenance will cause some on what you say, however i didnt mean that.
Why have an Auto if you are just going to use "D" all the time?

I thought that was the whole point of an auto

Hi Folks, auto boxes should be put into D for all normal driving situations, exceptions are long steep hills and descents also towing and icy conditions. Changing from 1-2-3-D like in a manual box will prematurely wreck the clutches (brake bands) and changing down at high speed will certainly wreck it sooner than later (possibly shattering the housing). If you want to change gear using the lever all the time why did you buy an auto box car? You don't need to press the O/D switch to overtake on motorways either, that's why there is a kickdown system. My friends garage in Liverpool specialises in Auto transmission work and would be appalled at some of the recommendations on how to use seen on this forum. If you need still to be convinced that D is the correct position to use for 99% of the time RTFM.

Most likely rip the mountings off.
Every auto I've had a manual to suggested that it could be rammed from D to 1 at 100mph if you wanted*, it will not go down to 1 until the roadspeed is low enough for 1 to engage, but when it does it will pop your eyeballs out of their sockets.

Also, the shock will likely break the one way clutch in the torque converter


*I never wanted to
I never mess with the gearlever unless it is to go backwards, or operate the transfer gearbox on a RangeRover



Incidentally, I rode motor bikes for 20 years before I discovered what a slipper clutch was


(the clutch drum is split in half, with a roller clutch that locks up when the engine is driving, and is free when the gearbox drives the engine, between the halves. In go mode, all of the clutch drives the back wheel. When changing down, the half clutch is weak, and will slip rather than lock the back wheel, or over rev the engine if you get too enthusiastic with the left foot)

Hi Mnl, some boxes will though and I have seen the results at my friends garage, I've seen the results of exploding torque converters too,the shifting from 1-2-3 etc also wears the clutches out. As stated before it's an Auto so let it do it's stuff as designed and built by the maker. Slowing down by downshifting as in a manual box style is not the thing to do in either type of box, brake discs and pads are many times cheaper and easier to replace than gearbox components. As a physics excercise try this, kinetic energy in the way of forward motion is not lost by slowing down it is transfered into heat on the brakes as you apply them, so if you use your gearbox to slow down the kinetic energy is dissapated inside the gearbox via the clutches etc hence they wear out in time due to the energy transfer process, try pricing up an auto box rebuild and compare it to new pads and discs.

opps that can of worms well and truely opened
Aauto gearbox rebuild can easily get to £1k plus the vat, i did say brake BANDs not Brake pads lol

i would rather have to change disks and pads than say have a power flush done on the box

my corsa b was a shed when i got, it wasowned by a single mum (i say no more)i had to have the box flushed and the selector switch replaced (a repair lasted 8 months tho) ot. the worst thing i had to do tho is hoover up glitter that was all over the back of the car

Ok i see we always have people on these sites who know it all, i get into trouble for doing this however here its ok.Just imagine my situation used to drive manuals now not able to as have no feeling in my left lower leg or foot, therefore have to drive a manual.
As I Have said before I have driven many cars in my short appearance on the this earth to know how to drive therefore i dont need "clever " people telling me how to drive, I have been complimented on my driving style and techniques by alot of professional drivers, and being a professional driver my self in buses and transportation of people i have been trained how to use an auto box. so if you lot want to drive your cars in "D" all the time then so be it. but dont please tell me how to drive mine.
As for costs of things Learners have been trained since the late 80's to use their brakes and not the gearboxes, however when i was trained i was told to use both as what happens when the brakes fail?????
My brakes on my car tend to last around 60-100k the gear boxes/clutches etc tend to last the life of the car, going on that you might think i know what im doing?

Using the box for braking in emergency is not the same as using it like that all the time, using it in D all the time except for exceptional enviromental conditions are the recommendations of both manufacturers and auto transmission specialists, If you want to drive it any other way please do it's not my box.

tbf its your car drive it how you want, go back 15-20 years and a lot of autoboxes where mechanical and a lot stronger (over engineered) to take a bashing, lots of the modern cars the autoboxes are electronic and in a way not as strong iirc the old mk2 cavieler used a had a chain in it for final drive

+1 on that flash22, with the old style mechanical auto's you were actually encouraged to use 1-2-D for a period until the ECU controlled boxes started to become more prevelant and todays boxes are not as mechanicallty strong as those of 15 years ago. Fortunately the Note has a true auto box and not CV unit or one of those awful vauxhall solenoid select manuals that were sold as auto units.

I passed my test just 3 and a bit years ago and I assure you I was instructed to use engine braking where approporiate; i.e. approaching roundabouts. It's actually quite a contentious point, as many people have strong contrasting views; many will cry of the environmental impact of engine braking being more effiicent, others bemoan the fact of the damage inflicted on the cogs. I tend not to do it as the effect is usually minimal anyway, but each to their own

On a final note, both of my previous automatics (a BMW 320cd and a Golf GT Sport) lived in "D" and seemed to be happier for it.

dare i ask?


what is the difference between using an auto like a manual - ie 1,2,3,D and those tiptronic flappy affairs, isnt that the same thing?

Hi Paulyt, tiptronic boxes are different in that they have more ratios to use (usually 5 or more instead of the std auto's 3 forward) and they vary greatly in design, especially over the last 8 years. Someeven incorporatea learning profilein the ECU to learn the drivers gear change habits and then change gear to match that profile, if there is no input from the driver in tip mode the ecu will revert back to auto even when the lever is in the tip position and the ECU will not let you up or down shift if the rev limits at either end of the spectrum are to be exceeded. The ratio clutches are different to cope with the tiptronic sytem i.e. stronger. If tiptronic boxes were the same as Auto's there would of been no need to design them, Porsche designed it and now earn big bucks licsencing it to everyone else. Oh and even more expensive to fix.

a lot of the tiptronic systems us a modified manual box a lot of them have dual clutches and can do fancy things like spinning up the next gear to match the other gears befor changing, cvts are a different ball game all together imho there weak and noisey and loose a lot more power compared to "normal" auto
