Mine was flashing non-stop for a while..however, it only did it after a few minutes of driving or acceleration; meaning that it did not flash when I first started the car. Took it to auto zone and the dude couldn't find anything in the computer...but I've been thinking about it and my guess is that you'd have to have the computer scanned WHILE the O/D light is flashing. It only makes sense...I reset my computer and it hasn't come back on since..if/when it does, I'll drive to auto zone, leave the car running (with someone in it of course
) and have them come out and scan it while the car is on and the light is flashing. If you have this done before I do, please let me know if it works. Hope this is of some help...
