Hey my speedo on my 89 has started jumping and dropping off to zero. I can be sitting still at a light or driving down the road and just all the sudden it will just start jumping up and down dropping to zero and back up....any ideas????

Thanks Rick
 
Either the gear in your tranny is broken, or the speedo is folding.
I'd try taking the cluster out and brushing all the contacts/bending them out a little to make them bite harder when you put it back. Worked for me once.

When my 89 did this it was soon after a tranny rebuild. I just loosened the cable from the side of the trans, jiggled it around a bit and tightened it back up. Problem solved. I think the tranny shop did not have it seated in the trans right.
