Question about 1997 Ford Thunderbird LX
Overdrive light flashes
will not shift from drive to overdrive
There is an electronic sensor on the outside of the transmission.Change the filter and fluid and replace sensor.The sensor costs around $150.
"High speed" probably is over drive,so if it is turned off,it can't engage.I have found that cutting the overdrive switch on and off can cause excessive wear and tear on the overdrive.
Regardless have the car scaned for a any codes thay is causing the problem. Just trying to keep the cost of repairs down by know exactly what the ECM has in it's memory for any malfunction that is creating your overdrive from engaging.
Good luck and hope this helps
