What would cause the overdrive light OD to flash on a Ford Windstar?

Answer 1

My 2000 windstar was just doing that same thing. my problem was corrected by changing the transmission range sensor. that is the sensor that is on the top of the tranny which is connected to the shift linkage.

Answer

I just went through the same thing on my mothers 2000 Ford Windstar lx.The overdrive light was continuous blinking the shift solenoids A,B,and C where malfunctioning the torque converter was malfunctioning the car was taking off with very little power.Before you go spending money on expensive sensors and getting a new trans and all that other spit.Check the fuse box under the hood of your car next to the batttery.... fuse # 19 is a 15 amp fuse. It controls your AX4S Transaxel,Vapor Management valve,Egr Solenoids and a bunch of other things like sensors and solenoids.I change the fuse and the car transmission is working just fine the overdrive is no longer blinking ,A word of advice always check your fuses in the car and the ones under the hood Always....SAVE YOUR SELF SOME $$$$$$$$$$$$$$$$$$.. FISHMEER....

My 95 Windstar van had the 0733 code, blinking OD light and felt like the engine was losing power. Mine would also jerk at times and make you feel like the transmission was going to fall out the bottom. Also it would start down-shifting on its own.

They told me it could be one of to things needs new transmission or it was the vehicle speed sensor.

Thank goodness it was the vehicle speed sensor (VSS).

I had this problem in a 1996 Windstar LX, dealer replaced the transmission range sensor / manual lever shift position (MLSP) sensor on the transmission; YMMV.

My trans wouldn't shift into 4th and was shifting in and out of 3rd-2nd gear. not real fun on a family outing in the middle of nowhere. P.S.- My LX has an Anti-Lock sensor indicator light on the dash (center) that tells me if I have a problem with the Anti-Lock system. HTH.

on our van it was the vehicle speed sensor.

Answer

check your Transmission Fluid level (engine warm and idling)

you over drive is actually off.... i have the same problem, try changing either the button in the van or it could be the actual over drive senor on the transmission... try not to drive fast speeds until the problem is fixed cuz u can blow ur transmission. my over drive like flashes once i hit about 60-80km followed with a check engine light

possibly because a sensor in the tranny is going bad or the OD part of the tranny is going bad. If the OD action of a tranny is wearing out, it will slip in and out of OD. anythings possible. Hope you find out what the prob is. Happy New Year.

That means there is a malfunction with the transmission. Sometimes it is just that the tranny is overheated.
