Overdrive light flashing

July 16 in Repair and Maintenance
i have a 1996 ford taurus dohc v6 147239 miles…when i get over 60 mph my overdrive light starts flashing and the car still drives find…i did have new transmission fluid and new fillter put in and the light was coming on before i did that and still comes on when i get over 60 mph

The transmission needs to be scanned for codes. Could be slipping, over-heating, speed sensor, etc. Might need to be overhauled depending.
