Certainly. It's been done for years before overdrive became a thing... it just means you'll turn higher RPMs at speed, and you'll want to drive slower if you're conscious about fuel consumption. I had no problems when I took my 87 Silverado with a Muncie 465 direct drive transmission on the highway.
Basically highway driving over 45 MPH when minimal power is needed Overdrive - hi-speed/low power
If it has overdrive use it! it is a "highway gear" it will make no difference what so ever until you get up to speed then it will shift into overdrive and save you gas!
Overdrive is the normally allowed position . It won't shift into overdrive until the speed is higher anyway , such as on the highway / freeway
Overdrive is the normally allowed position , but it won't shift into overdrive until the speed is faster such as on the highway / freeway
Overdrive is an extra gear assembly in the transmission that allows the engine to run at a lower speed (lower RPM) when you are travelling at higher speeds on the highway or freeway. For example, if I am driving my 1995 Explorer at 62 mph in drive, the engine runs at 2800 RPM. If I am driving at 62 MPH in overdrive, the engine runs around 2100 RPM.
Overdrive use depends on speed, not weather. Can you drive at overdrive speeds, use overdrive. If you can't, don't. Often it's sensible to reduce speed in poor driving conditions.
2 high, is 2 wheel drive which is where you should be when driving on the highway.2 high, is 2 wheel drive which is where you should be when driving on the highway.
Yes. Overdrive is best used with longer trips at relatively constant high speed. City driving, with lots of stops, starts, and slow speeds is not what the overdrive is intended for.
City driving or towing, off. Highway driving, on.
Overdrive ON is the normal position But if you are towing something or driving in hilly country where the transmission is constantly shifting from overdrive to drive , then you want to switch the overdrive off
"Overdrive off" is appropriate for hilly roads and mountains, also you can use when you need some extra performance, for instance, when you are entering a highway and you need to accelerate very quickly to reach the speed you need. Some models recommend overdrive off for towing. It's highly not recommended to use the overdrive function for everyday driving because it wears engines and transmissions out quicker.
Overdrive is the normally allowed position It won't shift into overdrive until the speed is higher anyway ( such as on the highway / freeway ) If you are towing something , or are driving in hilly country where the transmission is constantly shifting between overdrive and drive , you want to switch the overdrive off using the switch on the end of your gear selector lever ( P R N etcetera , the O/D OFF light will appear in your dash )
