No. You should not drive in overdrive all the time.
Overdrive is the normally allowed position ( it won't shift into overdrive until the speed is fast enough )
Overdrive allowed is the normal position
The car needs to go into overdrive unless you are towing something heavy which makes it shift between overdrive and non overdrive. It is better to allow the car to shift into overdrive.
Over drive is always to reduce engine RPM at Med to high speed cruise thus saving fuel. If this is an Automatic car just ignore the Overdrive and let it work. If this is a manual car use over Drive when maintaining a steady speed and the car will not "Labour" to do so.
For most drivers, Overdrive should be used full time. Its designed to reduce the amount of effort the engine needs to maintain speed. Whenever a lot of shifting is taking place, its recommended to only used Drive. Roads with a lot of hills, curves, or heavy traffic areas should not use overdrive to prevent damage to the transmission. Also, disengage overdrive whenever towing. There is not enough torque generated by the engine to tow while in overdrive. Towing while overdrive is engaged can cause damage to the engine and transmission.
why does the 1991 Lincoln towncars transmission not have overdrive?Instead of going into overdrive it seems to go into neutral.But if you take it out of overdrive and leave it in drive it never goes into neutral while I'm driving.
Overdrive is the normally allowed position , but it won't shift into overdrive until the speed is faster such as on the highway / freeway
You should leave the car in overdrive at all times, unless driving conditions dictate otherwise. The overdrive is intended to optimize fuel consumption.
I believe overdrive should automatically be enabled on any car. Overdrive allows a car to drive at fast speeds with low engine input (low revs) resulting in better gas mileage. The downside is that you lose torque. You should be able to turn it off for things like climbing mountains and using engine breaking to go down them. Unless you turn it off, it's already on.
When you want quick acceleration, or when you're driving at speeds lower than 3rd gear, which is around 35-45 mph depending on your car.
You Are Putting To Much Load On Your Engine. When It Starts To Stall Drop It Into Regular Drive. Also You Need To Drive At Slow Speeds In Regular Drive. At Speeds Say Around 50 MPH You Can Use OD. By Allowing Your Car To Slug Around In Overdrive You Are Doing Your Transmission In Amoung Other Things. Your Car Was Not Designed To Run This Way. Stay Out Of Overdrive At Slow Speeds. This Should Solve Your Problem. If This Does`nt Have A Good Tune UP.
