Transmission slip. O/d light started to blink and transmission clunks into gear. This problem seems to be very prevalent as a few of my friends who own 2000 to 2002 model Fords have had this problem. They have had their transmissions replaced or rebuilt. This is a very common problem and the manufacturer is ignoring the problem with their vehicles. 4r100 transmission. I believe this is a solenoid body or harness malfunction.
