Overdrive Light Blinking
I have a 1995 Ford Explorer and one day when I was driving on the freeway the rpms jumped from 25000 to 30000 and back and fourth with no hills, no load on, and no wind. I am asuming it is because it is jumping out of overdrive but not sure. Now every now and again it seems to down shift funny in town and the O/D Off light blinks. There is a button on the end of the shifter that can turn the overdrive on or off but it no longer works. Does anyone have any idea what the problem is? The switch? Speed Sensor? Tranny? Any suggestions would be great! Thanks alot.

I have a95 explorer and have been unpluging to battery to reset the code for the past 65000 miles. I replaced the throttle position sensor with no help. I heard it could be the powertrain managment computer (PCM $200) but have never changed it. I heard they changed some shifting values in the computer to widen the shift point so no errors show. Cannot confirm this though. I know of several people on internet with this problem and rebuilding tranny DID NOT fix the problem. I know for a fact there is a new part # pcm for this truck. alldatadiy.com has info on this . if you replace it get the latest and greatest. DO NOT drive the explorer with the light blinking. The trans is in limp mode, shifts hard. reset code. aslo make sure your tranny is not really slipping. go to alldatadiy for good info on this. I think there is a seal that gets pinched during assy. and it tells you to vaccuum check first.

when my wife's windstar started doing that it was the pressure control module, but luckily the wynns warranty covered it, although they were gonna try to fight it until the trans shop told them to cover 300 dollars of repairs now, or buy a trans later.haha
