I have a 2002 Ford Explorer w/approx. 120m miles. My o/d light started blinking and I got a "ck transmission" message. After exploring the internet I found over 200 other owners complaining about the same problem. I terrified 2 take 2 my Ford dealer after reading complaints from others. The light starts flashing after about 5 miles from starting the car.
