My speed sensor was working perfectly fine. The cluster is fine I got it like new. The speedo was working fine, now it just stays at 0 at all times ( obviously cause the speed sensor stopped work ) It stopped working right after I took it off to fill the tranny with oil. Now all of a sudden it stopped working. Any ideas?

 

Did you pull it back off to inspect it? Maybe a broken wire or something? Should have done that before posting.

 

Replaced the plug off a working one. Found out the speed sensor randomly went bad.. I dont understand how it can go bad from one day to the next?
