The o/d if left on will usually come on around 70 to 80 KMS ( 45 to 50 MPH ). Then the torque lock up will come on after that.

Why Trans vibrates in overdrive on 95 mercury what could this be?
Not too familiar with your particualr vehicle, but I will try to offer a few suggestions. Some vehicles come with overdrive switches in the cab that allow you to shut the overdrive off. These can short out. Your tranny might also have a selenoid that's going bad or perhaps you just need to flush the tranny out.

Why is overdrive before drive in a 1992 buick lesabre?
The overdrive is before the drive because as you ordinarly drive down the road your car automaticaly goes into overdive when you reach a certain speed. You use drive only when you are pulling a trailer or going up a large hill so it won't go into overdrive and put undo work on the transmission or motor. It is also a gas saving factor.

Is the Ford Escape always in overdrive?
The transmission defaults to overdrive, as well as enabling the 4th gear. There is a button on the end of the shifter that disables overdrive for times when it is rapid switching between 3/4th gear due to a certain speed etc. It can also be disabled to assist going up large hills for example or by improving engine braking properties. For normal use OD should be left on as is.
