my 93 aerostar did this, my problem ended up being the modulator valve on the transmission, a 13.00 dollar part at autozone, it was sucking tranny fluid into the motor, wouldn't shift right and was running terrible. you can tell if this part is bad by simply getting under the van, find the transmission pan, on the passenger side, on the pan lip(hard to see on a 93) there is a small hose connected to it, pull it off, if tranny fluid is in that hose valve is bad Another possibility is that the torque converter is bad. Thanks for answers. Oddly enough I replaced a fuse and overdrive worked??? *Where is that fuse located?*
usually it is the overdrive solenoid, but can be the connector to it, input to the computer, or the computer.
Not sure what you mean by "immediately". You do know that overdrive doesn't kick in until 50 mph (80 kmh)?
Overdrive is the normally allowed position so there is only one " D " on a 1996 Ford Aerostar If you push the button on the end of the gear selector it will shut off the overdrive feature and " off " lights up on the gear selector lever and it only uses the first 3 forward gears ( Helpfull )
There is a push button on the end of your automatic shift lever. Pushing it in causes the Overdrive to turn on and off.
posibbly the overdrive sensor we had a 88 ford aerostar that did the same thing
what would transmission not to shift in to overdrive
95 mitsubishi montero sr wont shift to overdrive why
On a 1998 Ford Taurus ; On the column shift the overdrive button is on the end of the gear shift lever On the console shift the overdrive button is on the drivers side of the gear selector lever below the button you have to press to shift out of PARK
The car needs to go into overdrive unless you are towing something heavy which makes it shift between overdrive and non overdrive. It is better to allow the car to shift into overdrive.
Because it does not have an overdrive gear.
Overdrive is the normally allowed position but it won't shift into overdrive until the speed is fast enough
That Is The Way Overdrive on your vehicle is designed to operate. Consider Yourself Lucky, You Are Not Overloading The Transmission By It Not Shifting Into Overdrive Until 45 MPH If It Shifted Into OD At A Lower Speed Say 25 to 30 MPH It Would Put Too Much Load On The Transmission That Most Likely It Would Fail Before Long.
