Your transmission might automatically shift out of overdrive while driving on the interstate because of low transmission fluid. This issue might also occur because of a bad transmission sensor or overdrive sensor.
why does the 1991 Lincoln towncars transmission not have overdrive?Instead of going into overdrive it seems to go into neutral.But if you take it out of overdrive and leave it in drive it never goes into neutral while I'm driving.
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
The brakes :)
The overdrive warning light might start flickering when you are driving because of low transmission fluid. This light could also come on because of tension on the transmission while you are towing a boat or trailer.
Overdrive is the normal position - if you are in hilly areas and find the transmission keeps shifting back and forth between overdrive and drive , you can use the overdrive cancel switch to shut off the overdrive feature and if you are towing something you also want to shut off the overdrive
More than likely the transmission has gone into overdrive.
If you are city driving, and stopping at many lights. The tranny might be shifting into overdrive constantly for just a few seconds before you have to stop again, which would cause excessive wear on an expensive transmission. Personally, in this situation I would disengage the overdrive.
Overdrive is the normally allowed position ( in overdrive the engine doesn't rev as high , the gas mileage is better , the transmission will run cooler etc. when you drive at higher speeds )
i know my Lexus turns off sometimes when i drive cuz my battery terminals r loose so it shuts off the car
Bad battery or alternator, or simply ran out of gas
No, on most cars the overdrive is always ON unless you turn it off.
