855540 2010-02-05 07:06:00 Recent discussion about using O/D or 5th gear around town prompts me to ask about something I was told recently.

I was told that it is better for the auto if it is left in O/D all the time.

I have mostly been in the habit of switching the O/D off when in town and also off when travelling up an incline where the auto kept changing up and down.That last bit makes sense.

I was also told that it is not a good idea to coast downhill in O/D. My Mitzi Galant changes out of O/D going down hill by itself some times.

Does anyone have any technical reason why the auto should be left in O/D around town and why it should be disconnected going downhill?

855541 2010-02-05 07:15:00 Nope I don't I try and buy manuals, but when I did have an auto I hardly ever used OD around town as it meant the car often was geared too high to drive properly at 50kph gary67 (56)

turning it off downhill = more engine braking

lower revs = better fuel economy

If you leave O/D on,you will tend to get the box hunting when going up hills,so best to use when cruising.

And when the managers are present,you tend not to?
