speedometer or metronome
The needle is bouncing like a metronome and increases in rate with increase in speed. A friend said it was a plastic gear at the transmission and I thought it was fracture in the cable. Anyway does anyone know? I have a C6 in it and just started on my way home from work.

Could be either. Pull the cable off tranny, look at gear. If it looks okay, then get your cordless drill and spin the cable and look at speedo. If it still jumps, then it's the cable.
If the gear on end of cable is all ground up, then likely gear inside tranny is just as bad. You'll need to replace both. There again, if the cable is bound up, it could have caused it, so check both parts.

I noticed the tic tic tic is coming from inside the display so I wonder if it is the cable or something in the gauge.I will pull the dash out to see what I can. Thanks guys this is annoying.

Had the same thing happen to mine. Replaced the cable...still did it. Replaced the speedo gear...still did it. Finally put the new gear in the tranny and fixed the problem. But hey at least now I know all the other stuff is new.

did you put the new gear in the tranny, or did you have to replace the one on the cable going into the trannY?

We all have brain farts sometimes.
And ya it still could be at the tranny. Mine did the samething. So no those are not the actual miles on my truck...theres like 27 more. haha. I would pull the speedo cable, inspect it and the gear on the end. If they look ok its probably the one in the tranny. You might still just go ahead and replace it all. Its really not that expensive and its easy. Just my 0.02.

It could be the cable. Generally what happens is the cable gets dry adding excess load on the nylon gear wearing it out.
If you have a mechanical tach driven by the distributer, they are driven the same way as the speedo. So trouble shooting will be the same.
Speedo replacement cables are cheap. But if you replace the outer housing you get rid of the old liner that some had. The liner quiets the noise better. Some newer ones use a teflon lining.
