There is a button on the left hand side of the gearshift just below the handle which engages and disengages the overdrive.
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
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
What can be the problem with the overdrive light flashing on and off?
The overdrive is "ON" when the light is "OFF". Notice the light for the overdrive has a slash through it.
If the overdrive's off light is on that means it's off. If it is off then the overdrive is on.
The overdrive light will be off when the overdrive switch is pushed in. If the light flashes then that's a trouble shooting code.
take it to a trans shop.

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.
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.
