So I drove my stang about 60 miles today and after about 45 the light started blinking, the transmission didnt make any strange noise and the O/D worked fine, I pulled over and shut the car off and turned it back on the light stayed off for about 10 miles and came back on again blinking just as it was before. Recently I changed the fluid and put a bottle of Lucas in. Fluid levels look good, could it be that the tranny is overheating? or has a bad sensor? Like I said it seems like its going through all its gears properly.
Hi I quoting from the big book "The O/D OFF indicator is controlled by the off/on message sent from the PCM over the SCP network". Whatever the heck that means. Maybe someone else can tell us what those abbreviations mean.
If the tranny is working, don't worry about it too much until we figure this out.
interesting, I read somewhere else that the O/D Light blinking was the equivalent of a check engine light for the tranny. Fluid level is good, nothing leaking. And the light doesnt start blinking until after I'v driven it 30 miles or so. I just drove it too and from work without it coming on. which is about 6 miles each way.
So same thing happened again today, drove about 30 miles and the OD light started blinking. The only mechanical thing I could notice happening was every once in a while the RPM's would rev up from 1800 too 2000 and then drop back down without shifting or anything while in cruise control going 60 mph on a flat straight road. I'm taking it to a garage in the morning for an inspection and a computer reset. Hopefully that fixes it.
Well you could reset it yourself, just undo battery (net then pos) wait 30 mins and hook it back up, that resets it then you can drive to see if it would come back on or not, but taking it for inspection would be a good idea
