Default Bouncing speedometer needle...

Hey guys, I had my speedometer rebuilt back in March because it was broken. Well ever since I put that new speedometer and speedometer cable in, the needle bounces up and down until I reach about 35 mph and then it acts normal. I installed everything correctly, maybe it's something with the gears in the transmission that turn the cable?

I have the same problem, I was told the cable is getting hooked on something. Sorry I can't help more then that.

Maybe I should try repositioning the cable housing so it's more straight.

mine shakes too, but it seems like its only at high speeds, but it doesn't seem like anything worth spending money on.
