Unhappy F350 7.3 Speedometer

Can anyone tell me where the speedometer sensor is?
The speedo doesnt work, can anyone tell me how to fix it?
I have a 1990 F350 7.3L 4X4 E4OD auto.
Thanks, Jeremy

you have a mechanica one off the transmission. It may be a broken cable. The sensor in the axle is for the ABS.

Wink speedo location

Since you have a 4x4 your speedo will be on the output cone of the transfer case. You should be able to see it if you sit under your truck and look at the top rear side of your transfer case.
Just a note since mine did the same thing.
My transfer case oil pump went south and the first symptom was the speedo began to go silly than the thing would slip outa gear at will.

Check your fluid for parts & pieces.

Good luck,
Eric

oops, he's right. I missed that. It's a cable about a quarter of an inch in diameter, and it runs from the transfer case to the firewall, and through a few other things if you have cruise.

jboard I guess you got the truck?

The plastic gear on the end of the cable where it goes into the transfer case, how does it look?

Hi Dave Looked at the cable I dont see a gear on the end of the cable just a small shaft that looks fine. Is there suppose to be a gear on the end of the cable? If not then is the problem internal?
Thanks, Jeremy

that is most certianly your problem then. There should be a gear on that cable for sure. You'll have to replace it, probably with the help of a speedo shop to get the right one.

I would pull the output shaft cover and check the condition of the plastic gear on the output shaft also.
