I may mean that a module governing your transmission is not functioning properly. We had a similar thing happen when the downshifting occurred spontaneously. Replacement of a $350 electronic board solved the problem.
More simply, you probably only need to replace the Vehicle Speed Sensor (VSS). On my Windstar the speedometer would go to 0 and then would not shift out of low, too. This only happened when the sensor got hot; once it cooled it would work normally again...for a while. I replaced the $25 VSS and it has worked fine since.
The overdrive warning light might start flickering when you are driving because of low transmission fluid. This light could also come on because of tension on the transmission while you are towing a boat or trailer.
Why are you driving a Windstar!
Customer had a similar problem with a 99 Windstar. Stopped pulling while driving it. Had it towed to me and I replaced the torque convertor. Problem fixed.
alternator
My wife did the very same thing to my 2001!! (seriously! ;))My trusted transmission repair shop reported the torque converter had pretty well self-destructed.$1600 later we were, and ARE, happily "on the road again" (Willie Nelson)
sounds like your transaxles or transmission It could also be a bad wheel bearing - See "Related Questions" below for more
An automatic transmission is better than a manual transmission for city driving. It cuts down on the fatigue of constant shifting and reduces rollback.
when the transmission is not shifting or changing out on a 1.8 jetta
stop driving that vehicle and have it towed to a reputable repair/transmission shop - NOW!This vehicle is at high risk of being severely damaged.
The alternator died first and drained your battery shortly thereafter.
i have no spark from coil..i was driving down the road and it just quit
Try this solution. http://www.leckemby.net/windstar/windstar01.html It seems that Windstars have a problem with the intake manifold.
