Just replaced the speedometer cable on my '90 'vert (with '88 engine and transmission). I used a NAPA branded cable. Now, the needle wiggles fiercely at speeds below 62mph. Anything above that, the needle is rock solid.

Did I not secure the cable well enough? Maybe I over tightened the cable to the trans? Does the cable need a couple hundred miles to break-in? Or... is my cable a POS and I should go buy the OEM cable?

I'm going POS, but I'm not sure because I've never had to replace one

did it do it before?

Make sure it's in the back of the gauge cluster all the way.....

I think I may have prematurely panicked. I've put about 200mi on it. Below 30 is solid, 30-50 has a slight shimmy, 50-60 is continues to be wild, and 60+ is still rock steady.

I think it may have just been stiff since it was wound up in a box for who-knows-how-long.

I think it's the gauge, not the cable.
