is it good to use overdrive button in city daily driveing?

Is it good to leave it always on? or press it about 40km and press it off form stop to start?

If always using overdrive for daily driving in city, is good for the tran?

obviously you dont know how it works

the "o/d" button is the overdrive SHUTOFF button, not the TURNON button. just put it in D and go, it will pick the correct gear, and you turning it on or off will mabe 0 difference to your driving UNLESS you are pulling something and your transmission is switching between OD and 4 (3 in a 4 spd), or climbing hills and it is doing the same
