Overdrive....

On the highway.

I've heard several different opinions as to when you are supposed to use it. I'm looking for the correct one. I drive a 95' Nissan PU LX if that's any help.

(Father forgive me, I'm about to question the wisdom of The Elder.)

If that's the case, why did Nissan put a button on there to turn it off? Are there no circumstances under which you might want to over ride the computer?

Well, actually, they put the button on there because they didn't want to design the shifter to allow you to actually select all of the gears the normal way. That button is the only way you can select "3" on the transmission. For a different approach, take a look at a recent Honda. The shift lever has positions for 1,2,d3,d4,d5 (if its a five speed). d4 and d5 are both overdrive gears.

I turn the OD off in the city and on country roads that have alot of hills and valleys. I'm sure in some way it's easier on the tranny not to have to shift in and out of 4th all the time.

Towing a load, going up a slight incline, etc. Situations where the tranny will go back and fourth between overdrive and third excessively.
