Fuel economy will suck. Unless you drive in the mountains then it will help going up.
No, on most cars the overdrive is always ON unless you turn it off.
Overdrive is the normally allowed position Until you are travelling around 50 MPH / 80 KPH it won't shift into overdrive anyway If you are towing something , or driving in hilly country where the transmission is always downshifting , then you can shut the overdrive off and the O/D OFF light will light up in your dash
Unless you are towing something or encountering steep hills (do you live in San Fran?), you should always be in overdrive. The lock-up into overdrive won't occur unless you are going fast enough, anyway, so there is no reason not to keep the gear selector in OD.
For cars that have an automatic transmission, overdrive lockout turned 'off' (overdrive will engage), is the default option.
In normal driving conditions operating in Overdrive is fine and expected. In conditions of heavy loads or pulling something i.e. (trailer) overdrive should not be used. The transmission will shift up and down alot and in turn possibly overheat the transmission fluid creating extensive wear on the transmission.
its always best to use your overdrive when on highways at higher speeds
When entering a freeway you should always look and make sure that there is an opening for you to enter. You should watch the surrounding traffic.
It allows the car to operate at lower revs making for a smoother drive and better fuel consumption at higher speeds. The gearbox will shift into overdrive itself, so it is always best to have it switched on in normal driving conditions. You only need to switch off the overdrive when you need greater engine braking or are towing a heavy load.
Your vehicle has an overdrive button on the shifter maybe. When you start your vehicle, overdrive is always on. When you tow something, you want the overdrive to be off, otherwise the transmission will run hot and that will lead to bigger problems.
No he used to use the overdrive. Before the R.K.O it was the Overdrive and the Complete Shot
In simple terms, overdrive is the final/cruising gear. It reduces the power output by lowering the gear ratio. The overdrive mechanism increases fuel efficiency, and saves strain on the transmission and the drive train. When the vehicle is started the overdrive is always on, but it can be turned off by a switch button, which is often located on the shifter. Turning the overdrive off will prevent the vehicle from shifting into the overdrive when traveling at the speed of around 40 MPH. It is recommended that the overdrive is constantly on under normal driving conditions. It should be turned off when, for example, hauling heavy loads or going up a long gradual incline.
The punishments get more severe when you have previous DUIs, but driving under the influence is always serious. It's really dangerous and irresponsible.
