how much would a transmission replacement be on 2002 Ford Taurus

the car will not go into overdrive

Asked by for the 2002 Ford Taurus
It would really just depend on what the cause is, if you have a bad sensor or solenoid causing the issue then it shouldn't really be more that 3 or 4 hundred dollars. If you bring your car by one of my locations we will drive and scan your car for free and let you know what it will take to fix it.
