Just as the title says. I have no idea what it could be. The car is an 86 T/A with a 700R4.

From what I've been told, it has a speedo cable and that it works both the speedo. and odo.

 

I've never actually seen someone complain that the odometer isn't working.......

I fail to see a problem.....

 

Welcome to typical/common thirdgen problems. I suspect that 75% of all trip odometers are broken (the mechanism inside the speedo head is fabricated from plastic). I've heard they're repairable, but I have no personal experience.

Not really worried about it being broken, just wanted everything to function properly. Broken **** is just a pet peeve of mine

 

same here,i hate anything outta place & anything broken on mine too....might wanna try the electronics board..might get some more info on it...i know i had my "strange azz question" moved there & got some good responses...just a suggestion

 

My trip odometer is broken too. I asked about it before and was told you can't fix it. I would love to know how to though. Try to find one off ebay or somewhere like that is all I can say.

 

Had that happen to my Bird once. All I did was drop the cluster, pull out the speedo and just blow it out--worked fine after that.
Might be some plastic debris from the plastic gears inside or just a large piece of dust or something.

 

i no the feeling it drive me up the wall, mine dont work along with my speedo,rpm,oil. i even tryed 2 swap cluster. good luck, let us no if u find the problem.
