[APA]

Sup guys

just wanting to know

at moment i am driving with it on

is this correct?

or is it better to have overdrive off? stoopid lil orange overdrive off light lol

thanx adrian

:burnout:

With Overdrive OFF you will get more power but use more petrol as it's a lower ratio of gears.

i wonder what the ratio of autos and manual of imports are that come into australia??

Overdrive is for highway use. Around town you wouldn't use it.

Overdrive is like an extra gear for the auto that was designed this way to reduce fuel consumption on the highway the main reason that people leave it turned off in town is because you need to get to between 80 or 90 kph before overdrive kicks in!

And if you cruise at around 80 - 90k's (mine changes as low as 70kph sometimes) the overdrive can change in and out of gear (rather unecessary at this speed) and this constant changing between 3rd gear and overdrive severly wears out the overdrive!

P.s PVA-glue towing a trailer or having two chicks in the car is not a good reason to use the overdrive! (and you wouldn't benifit nothing from it unless you were doing more than 80 - 90 k's) maybe your thinking of the power button (this changes the rev range at which the auto changes gear (redline gear changes if under heavy acceleration) and also early drop-down which can be quite fun! The hold button just makes it so that under hard acceleration the auto won't drop-down a gear!

Exactly right....I was going to type something along those lines but I couldn't be stuffed.

An overdrive is any gear with a ratio higher than 1:1. Top gear in most manual is overdriven too.

The button just locks out the forth gear.

but i still dont' see why people would want to drive with it off .. i mean the revs are much higher ... maybe about 600rpm or something like that which is really noticeable ... which means you could stay at the same speed at a lower rev and therefore be more feul efficent ... so why the recommendation to drive with it on around town?? i only ever turn it off if i want to go a bit faster.

By leaving overdrive on driving below 80kph you will do harm to your transmission.

Overdrive is simply for highway use.

but the rev is much higher ... and u waste petrol??

The amount of petrol you would save would be very small.

[hippy]

ok i will do a test ... i have to fill her up today anyways .. i will use my normal petrol as i always do and i get around 450 - 500 depending how i drive ... i will always use overdrive off when in normal traffic ... say anything below 80kmhr and turn it on anything over ... i will give u guys the results in say 5 days time which is the time it usually takes for me to use a whole tank.

oh another thing ... can u guys with auto gtst's tell me what rev u change gear at for each gear with overdrive off??

PLEASE PAY ATTENTION!!!

Having overdrive turned on or off will make no difference to shift points, fuel economy or power BELOW 80 kmh. If you are driving in an 80 k limit, or below, leave it off, as on and around 80 k it will be cutting in and out and will premarturely wear out clutch packs in a transmission. My O/D is always off, unless im travelling at 90 k or more....

The power buttong is the one thats will change shifts points, and the only thing that changes ratios is the torque converter because it actually can give you a 2:1 ratio in torque multiplication.....

maybe its just my car but it is different ... it revs higher all the time ... as soon as i press the overdrive it will change gear and this is well below 80 ...
