My overdrive light keeps blinking. I have reviewed many different answers but nobody has a direct and correct answer. Here is a video of what my overdrive light is doing.
As of right now, no issues with the transmission. I disconnected the batteries for 24 hours and the speedometer is working. SOMEBODY HELP

 

mmmm Blue interior!!! Take care of it, parts have been discontinued.

You need to get the codes scanned. When that flashes there is a code stored. Cheap autozone readers will not pull the codes.

 

The blue interior is quite nice... I may have to go to a transmission shop... I just don't want to drive it in case I am ruining the transmission.

 

Where are you located? Someone may be close to you and be able to scan it for you...



245k on mine...

 

I'm in Baltimore... Is it something I could buy online or ebay? I could always need it in the future and since the truck at only 110000 Miles its surprising.

 

Click the Auto Enginuity link in my sig...

Seems like a bit of money, but it is the single best thing you can buy for your truck if you have plans of keeping it.

Otherwise if you can find a used/cheap superchips or something like that, they can read and clear codes...

 

dang thats a ton of gauges. did u notice anything funny when you drove it like odd shifting? mine started to flash when there was some moisture in the wiring a wire had become striped and the moisture made it flash then it went away after a while then came back. but its always a good thing to check your codes i just got lucky on mine

 

i'm in waynesboro pa about 90 minutes from you and could check it if you dont mind driving over here. mine did this too and the tranny would slip really bad. i ended up having to buy a new trans. 717 404 9617 call or text

 

Im nervous to drive it such a distance... There is no tranny issues that I feel yet, I just am waiting for an issue to pop up... I'm gonna stop by a local tranny shop and see if they can run a test on it.
