O/D Off flashes on and off

It has only done it once so far. I just got the car back from getting the gasket on the tailshaft replaced and I was coming home and it just started flashing on and off. It hasnt done it since I turned the car off and started again but I am just curious as to what will cause that?

Re: O/D Off flashes on and off

It usually signals a trans problem. Sorry for not being specific.

I would say drive it & if it does not come back you are ok.

Re: O/D Off flashes on and off

Just took it for a drive and the son of a ***** came back on. I am starting to get pissed with this car. I just got it back from having it serviced and a gasket on the tailshaft replaced.

I just took the positive battery cable off and plan to leave that off overnight to see if that might be it.

As far as I can tell the tranny shifts fine.

Re: O/D Off flashes on and off

Brent,
Something I found.

It means the EEC has detected a problem with the transmission, or the control circuits. The most frequent cause is overheated ATF

How can it be overheated?!?!? It just got serviced and has fresh tranny fluid in it.

And Brad if you want to give me the 1100 dollars to buy the 5speed swap then I will.

Is the fluid circulating properly?

I am going to have to jack it up tomorrow and look at it while running.. I dont understand why it wouldn't be...

Would it throw any check engine light codes if that was the case? My chip has the check engine light turned off I believe so I wouldnt know.

Re: O/D Off flashes on and off

has your tranny been slipping at all? that would cause some overheating.
check the trouble codes.

Re: O/D Off flashes on and off

scan the codes to see if there is anything pending that has not set the actual light, but turning off the CE light with a chip is not something that is usually done

Re: O/D Off flashes on and off

Alright took it back up there.

He hooked it up to a code reader WHILE THE DAMN LIGHT WAS FLASHING

and it did not spit out any code about the tranny, just the usual engine codes I have grown to love owning Fords (EGR)

So what now? The car shifts fine, there are no codes pertaining to the tranny while it is flashing.... is there any sensors I need to check?

If so where?

Re: O/D Off flashes on and off

Maybe a short in the sensor itself? Bad light? If everything thing is fine, I think the sensor itself is suspect. It's about time for all of your sensors to go out at once anyway...

Re: O/D Off flashes on and off

Where is the censor that controls this? It is possible we hit it pulling up onto the trailor or maybe it was shorted when we drained the tranny fluid.

I need to know where to look

Re: O/D Off flashes on and off

Ive heard that when it flashes like that it can mean that your CPS is melting (melted) so you might want to check that.

Since the problem started after replacing the tailshaft gasket, check the two speed connectors in the back of the tranny....one is the Vehicle Speed Sensor (VSS) and the other is the Output Shaft Speed (OSS) sensor. A problem with either one should have showed up in the scan though.

The other reason for the O/D to blink is to have a problem with the EPC solenoid, it should show up in the scan also. Looks to me like they might be avoiding responsibility. My 2

I was there when he scanned the codes. It only turned up engine problems.

I was told that my CPS problem could cause it to go off.

The CPS problem is being fixed as we speak so we will see when I get my car back.

Re: O/D Off flashes on and off

Make sure the EEC is reset after the repair and let us know what happens.
