It's strictly a personal choice. If the relative speed at which you are travelling in town (approx 35 mph to 45 mph) causes the tranmsission to constantly "hunt" back and forth between 3rd and OD, and you find it annoying, disable the OD while driving at those relative speeds
Yes, unless you are pulling a trailer.
If you are driving for a period of time over 45 mph then use overdrive. If you are driving under 45 mph or in traffic that is speeding up and slowing down over and under 45 mph then do not use.
Overdrive is the normally allowed position . It won't shift into overdrive until the speed is faster anyway . On my 1995 Ford Explorer it doesn't shift into overdrive until I'm travelling about 50 miles per hour ( if you are towing or driving in hilly country where the transmission is constantly downshifting then you don't use overdrive )
Yes, under most conditions you can use overdrive. If you are pulling a heavy trailer, or the vehicle is heavily loaded, I would recommend you don't. If at anytime you a driving loaded and the transmission starts changing gears constantly, you should disengage the overdrive.
Overdrive is for highway driving, which is great for gas mileage. Also, not to use overdrive when going up or down hills because it makes your transmission work harder. That's what I was told anyways.
Yes, you can use overdrive in your car when driving in the snow. Using overdrive helps the car maintain better traction in slick and icy conditions.
when ur driving in the city it is adviced to put gears in drive rather than in overdrive position..the reason being overdrive is a system that allows your gears or drivetrain to use the lowest gears /ratio for fuel saving cruising, with it off , it holds to a higher gear ratio so you have more power and torque to tow or climb hills..but it prooves to be horrible while driving in the city..
I would use the overdrive during normal driving. How ever if you need that little extra power then i would just turn it off. haveing the overdrive on all the time during normal driving " not pulling a boat or another car" should save you a little gas. just think of your overdrive as a half gear need more power go to the full gear
not recommended overdrive is for cruising at highway speed
It's not recommended to use overdrive on a constant base. It stresses too much the engine as well as transmission.
No. Overdrive should be turned off when towing any trailer.
As a general rule, YES! The only circumstance I know of that this changes is when pulling a trailer. Then its recommended to take it out of overdrive, unless you are finally on the highway and at cruise speed for a good distance.
