The overdrive ON / OFF switch is located on the end of your gearshift lever
( P R N etc. )
Check transmission fluid level Try changing transmission fluid and filter
default is of course 'on', does your overdrive switch not work? Overdrive should be saving on gas mileage...To change, you would likely need some way to access the cars computer. Goodluck with that.
there is a button on the end of th gear shift that you simply push in..
The button does not switch from Overdrive to Automatic. The button just turns the overdrive off. Overdrive is not a separate drive system as your question implies. Normally you leave the car in overdrive mode. That way the transmission shifts into overdrive at highway speeds, thus saving fuel. If you are saying the transmission is stuck in overdrive and it will not disengage then seek out a A/T professional.
When it has been pressed and the light is on, the transmission is limited to 3rd gear.
Take it in. There is either a problem with your transmission or with the overdrive switch itself. Overdrive switch should be a lot cheaper to fix. I'm assuming the light not only goes on, but the overdrive physically turns off as well when the light is on.
Overdrive ON is the normal position But if you are towing something or driving in hilly country where the transmission is constantly shifting from overdrive to drive , then you want to switch the overdrive off
Chances are that the overdrive solenoid (forgive my spelling) inside the transmission needs replaced. Not a job for the light-hearted.
On the Nissan 240SX the electric overdrive switch is located on the right side of the transmission. Overdrive allows shifting into the auto's fourth gear.
The 2000 Ford Windstar ABS relay switch is located on the firewall in the engine compartment. The relay switch will be on the passenger side of the engine compartment.
Overdrive relay switch behind the middle air vents..... Manual Transmission: the wires sometimes break if it is the type with the button on the gear/knob/ stick........... if it is a manual transmission.......the switch on the gearbox which tells when 4th gear is engaged can be faulty.....and will not allow the overdrive to engaged.
if their is no slipping or any other transmission issues and it is just only the loss of overdrive try replacing the brake light switch
