Asked by Carlee Jun 01, 2019 at 02:07 AM about the 2005 Ford Explorer

Question type: Maintenance & Repair

When the "O/D off" light is on in my 2005 Ford explorer,
does that mean the O/D is on?  When I first started the
truck the light is not on. You have to push the button on
handle for "O/D off" light to come on. Basically I'm asking
should I drive with the light on or off?

Default setting is on, so when you start it up at anytime the overdrive is turned on, when you push the button that turns the overdrive off and turns on the reminder light that the overdrive is off. If you are driving at speeds under 45MPH the overdrive should be off, so light is on, also never tow with the overdrive turned on, that will fry a transmission really quickly. Overdrive is designed to operate at freeway speeds so above 45MPH turn it on, so the light is off. Backwards I know but that's Ford for ya.

Hi Carlee, t shoes is pretty much dead on! However I will say that with my OD switch, I have towed just fine with my outfit ( 96 F150 v 8 4 x 4) with ease BUT the speed was kept way down ( high velocity, low rpm). yes, I was able to tow with my OD. Although I was flattered to have the full contained '72 travel trailer, I no longer have it. My vehicle is doing just fine. Good luck, from Utah


Just drive it. If you are towing something switch the O/D to off.
