91' buick regal limited am I suppose to put it in over drive on the freeway?

hi I have a 1991 Buick regal limited... several people have told me that I am suppose to put the car in regular drive on the streets and over drive on the freeway...is this true?91' buick regal limited am I suppose to put it in over drive on the freeway?An automatic overdrive transmission is a 4 speed automatic. You should keep the car in overdrive at all times. The transmission will shift in and out of overdrive automatically as needed!

The only times that you should shift to drive is if you are traveling at a speed where the car is constantly shifting in and out of overdrive ( usually about 37 MPH) and it bothers you, or if you are towing a trailer! You may also want to downshift on a extreme downhill grade!



When you drive in overdrive, the transmission shifts and performs the same as in drive, until you get to higher speeds. It is the same as having a three or four speed (OD) manual transmission. The first three gears are the same, you just have the fourth (more efficient) gear to go to in the 4 speed!91' buick regal limited am I suppose to put it in over drive on the freeway?
Yes, in fact select overdrive even when you are not on the freeway. I steps up the gearing or shift rate of your transmission and will save you gas. The only time that you need to put the transmission selector at D is if you require a faster start off the line or more passing power. Back in this time I usd to sell this car for a new car dealrship and am very familar with the vehicle. Enjoy it is a good car91' buick regal limited am I suppose to put it in over drive on the freeway?Overdrive will give you the feeling of turbo boost on the freeway... but will bite at your transmission. Overdrive is good in high trafic-stop and go situations to save gas ;-)



Cruise that 91B Regal... don't try to push it unless you plan on replacing parts for street modifications.
don't listen to them. they don't know what there talking about. overdrive is for when you are going up a hill, a very steep hill.91' buick regal limited am I suppose to put it in over drive on the freeway?Correct. Overdrive improves gas mileage but gives up some pulling power.91' buick regal limited am I suppose to put it in over drive on the freeway?
Yes it is true. But when I took drivers ed 12 years ago they taught us to keep it in overdrive all the time.
Does not hurt a thing to leave it on overdrive at all times. In fact can save you some gas if it is allowed to upshift to the higher gear above 35. The other drive is for long hill downgrades and if pulling a trailer to prevent constant shifting.91' buick regal limited am I suppose to put it in over drive on the freeway?
There is no specified rule its your choice ~~
hell yeah it's true!!! if your travelling about 100+ kms you should put it in over drive (it acts like a sixth gear) and takes some strain out of the cars 5th and saves you a s#*t load on fuel!
uhhhh yeah. true you lose some pulling power but say you decide u really wanna get on the accelerator on the freeway if you do it in regular drive you will eventually blow up the motor my friend did the same thing in his f150 when we were racing
