On the Ford Explorer , on the end of the automatic transmission gear selector lever ( park , reverse etc ) there is a push button that allows you to turn off the OVERDRIVE feature if you wish
It should. If there is a switch on the dash or shifter lever that is labeled OD off, you will know for sure.It should. If there is a switch on the dash or shifter lever that is labeled OD off, you will know for sure.
The OD light on dash stands for Overdrive. There is a button (usually) on the end of the turn signal lever. Some cars the button or switch is on the dash. If you push the button/switch the light will change to OD or OD on (may even go out) then you will be in overdrive. Being in overdrive is good except for steep hills or pulling a heavy load.
OD= Overdrive. There will be a switch to engage/disengage the OD located on the shifter, or on the console in close proximity to the shift lever. It should even have a marking on it.
sounds like you need to replace the OD switch in the shifter.
I have a 1996 Prizm LSI and the OD switch is a small round button on the side of the shift lever. You could have accidentally switched it off and that is why you get the light.
On the upper dash right of the steering wheel next to the overdrive (OD) switch
i had the same problem,mines a 89 too. that being said,mine has the switch on the Console,Not the shifter,and i discovered i had to run a power supply to the middle pole,then switch works fine. i did this by running a Good wire from fusebox to switch,from Power lead that Only comes on when car is running. otherwise,it will stay on all the time n kill your battery. anyone know what that button on the Side of the shifter knob is actually for?
The OD of switch is a simple on/off switch input to the engine computer. You should be able to check it for a 5v feed and see if it has continuity when pressing switch.

Means the switch that stops the trany from using the overdrive is shut off. Usually a switch on the shifter.
Check the fuse. If it has a manual OD switch to turn off and on be sure it is on.
