Check for a blown fuse for the tcc (torque converter control).
When the overdrive button is pushed, the overdrive is shut OFF. ======================================================= But if you push the button again the overdrive is allowed , so it would be ON So , if you are on the highway or freeway where the speed is higher just look at the RPM on your tachometer to tell if you are in overdrive because the RPM will be lower
bad fuse or bad switch
The button turns the Overdrive on and off. Leave it on unless you are towing something.
There is a push button on the end of your automatic shift lever. Pushing it in causes the Overdrive to turn on and off.
To turn off the overdrive in a 2005 Lincoln Navigator, locate the gear shift lever. There should be a button labeled "O/D" (overdrive) on the side of the lever. Press this button to deactivate overdrive; the dashboard will typically display an "O/D OFF" indicator to confirm that it's turned off. To re-enable overdrive, simply press the button again.
It means that the overdrive is turned off. most likely someone hit the overdrive button by mistake or pushed the button while using the vehicle to tow and never pushed the button again to turn overdrive back on. On most cars the button is at the end of the shift handle.
take it to a trans shop.
Usually light is on as a warning it is off. Most have on/off button on 1 of the stalks.
Overdrive is the normally allowed position If the vehicle is shut off and then restarted , the overdrive will be allowed To turn off the overdrive feature , the button on the end of your gear selector has to be pushed and the O/D OFF light comes on in your dash ( if you push the button again the O/D OFF light will go out and the overdrive feature is allowed )
Your vehicle has an overdrive button on the shifter maybe. When you start your vehicle, overdrive is always on. When you tow something, you want the overdrive to be off, otherwise the transmission will run hot and that will lead to bigger problems.
you probably have a button or switch to turn overdrive on and off, it may be on the end of your shift lever, you probably want to keep the overdrive on, save you some gas, hope i helped
If the light says off then your overdrive is turned off, push the button again and the light will turn off and overdrive will be on again.
