Your overdrive light could be faulty. You should check your fused and replace the one associated with the overdraft button.
Overdrive is the normally allowed position so you don't see the light on If you turn OFF the overdrive , the overdrive off light will light up or if there is a problem the overdrive off light will flash
The overdrive off light flashing - indicates a malfunction has been detected
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.
keep the overdrive shaft button pressed, there is a panel light called "O/D" that should light indicating the overdrive is OFF. In that case make sure the light is OFF which means overdrive is ON.
That will turn off ( or turn back on ) the overdrive feature of your transmission When the overdrive is off , so the transmission only uses the first ( 3 ) gears the O/D OFF light will light up in your tachometer . Overdrive is the normally allowed position so if you shut the vehicle off , the next time it is started the overdrive feature is allowed or if you have shut the overdrive feature off just push the button again to turn the overdrive back on
Normally the overdrive is allowed , so the overdrive OFF light does not light up When the overdrive is switched off , the overdrive OFF light will light up to let you know that the overdrive has been switched off
On the end of your gear selector lever ( PRN etcetera ) is the transmission control switch . Overdrive is the normally allowed position , but when you turn the overdrive off ( the O/D OFF light will light up just above and to the right of the speedometer and if you have the digital dash it will show " overdrive off " to the right of the speed indicator )
overdrive is turned off. This is usually controlled by a button on the shifter knob. Press it to turn of the overdrive, push it again to turn it back on.
off -------------------------------------------------------------------------------------------- If you are not towing a trailer you would want the overdrive to be ON so that your engine RPM is lower **( you will not see the O/D OFF light in your dash ) **
The overdrive is "ON" when the light is "OFF". Notice the light for the overdrive has a slash through it.
Overdrive is the normally allowed position It won't shift into overdrive until the speed is faster anyway ( on my Ford EXPLORER I have to be doing around 50 miles per hour ) If you are towing something or driving in hilly country where the transmission is constantly down shifting then you want to turn the overdrive off and the OFF light will appear in the end of your gear selector lever
If the overdrive's off light is on that means it's off. If it is off then the overdrive is on.
