Speedo Problem

Hi, before I tear into this cluster has anybody had this problem or could maybe point me in the right direction on how to repair. The speedo works but will not drop below 30mph or travel above 65mph and reads correctly in that range. Everything else appears to work properly including the odometer and the car runs fine. Any suggestions ?

Thanks, Wayne
 
Try this

Before ripping the cluster out try replacing the vehicle speed sensor/Trans speed sensor on the tail shaft of the transmission. It cost around 10.99 at most auto parts places. I had some weird readings from mine an this fixed it. Pretty cheap way to figure out which it is. Takes about 15 minutes to replace it. Just remove 1 10mm bolt from the hold down bracket, remove the speedo gear and replace it on the new sensor. Bolt it back in and see what happens.

If you pull the speedo I will bet it is the "infamous" part# sticker that falls off and gets stuck in the works.

Helpful.............:rolleyes:
If you are getting sporadic readings like that, it could be the gear,
or
You might wanna try pulling the cluster first(what I would do, it worked for me before) and disassembling it. The 3 large pins often do not make contact well with the terminals in the cluster housing, so I gently pry those things(the terminals in the cluster housing, not the pins in the odo+tach) so that they really bite into the pins on re-assembly. Also take a small wire brush and by hand gently rough-out the traces on the cluster where the plugs + card on the back of the cluster housing plug into, those terminals lose their squeezing force over time. This technique solved the problem on 2 of my 4 birds.
If you are getting an accurate measurement and NO BOUNCE of the needle at a certain range of speeds, it is less likely the gear in your tranny. Could be the speedo itself. But that's the second thing I'd replace if the cluster trick did not work...
good luck!
