OD on or off?

This is just a poll really. I just want to hear what people do. Do you all drive your atx trucks around with the OD off or on usually? I'm talking around town not towing anything. I only turn the OD on when I'm on the highway. When I'm around town I turn it off.

Just curious to hear from you all.

Since every time I turn the truck on, its on. I just leave it on. The only time I really turn it off is when driving on steep grades. More power going up and not having to ride the brake coming down. Also with it being electronic I figure the less I mess with it the less of a chance of it breaking.

ya I agree with daksport. the only time I turn it off is when towing a trailer or goin up a steep hill.

Same thing here.
Unless I'm going up a steep hill (or towing, which I don't do), I just let it do its thing.

I was told by a wise transmission man once that you should dissable the OD in city traffic. When in OD the 'freewheel' action when coasting causes the sprag clutch to wear sooner. I have actually seen a few cases where these things break or just basically melt down.

My other thought was that the transmissions shifts more with the OD on. This is due to the truck needing more RPM to up a hill or to accelerate where if the OD was off it would still be in the powerband.

Thats a good lil tid bit of info to have. I will certainly keep that in mind. Fortunately I don't do much city driving if any with my Dak.

If most, say 50% to 75% of your driving is local city driving below 40 mph, you should turn it off. If most of your driving is highway above 45 mph, then it would be best to leave it on. Turning it off around town prevents the lockup converter from constantly engaging and disengaging, which causes wear. It has been my experience that using overdrive around town has very little impact on fuel economy.
