I've had 3 different speedo's in my car and they all bounce (3-5mph) the needle between 20 and 70mph. I am going to redo the tranny next week and was wondering if it might be the cable or the speedo drive causing the bouncy needle thingy. Either way I'd like to fix it when I have the car up on stands.

Very likely a bad cable.

Sounds like a kink in the cable. Once it is there, it will always be there. Change the cable and it should resolve.

Mine had this problem when the angle-drive was leaking tranny fluid into the cable. I'd replace the cable and/or get the speedo serviced and it would be back again very soon. The direction of rotation on the cable just wicks the fluid right up into the speedo and gunks up the whole thing. I solved the problem by going to an electronic speedo and then disassembling the whole car to restore it. If it ever gets put back together I'll deal with the angle-drive then.

Pull the cable at the angle drive....put a drill motor on the cable end...and spin it up...if it still jumps...cable. If it works fine it's most likely the angle drive.

Where I grew up (just outside Yellowstone) we all had bouncing speedos because of the cold winters. If you use reverse when it's -30F outside the 'wire rope' (speedo cable) turns against the twist and unwinds and from that point on is always springy hence the speedo bounce.

Yep, what he said. Nothing wrong with the speedos; your cable has a kink in it. |

Once had that problem on an American car; took the cable out, cleaned and greased it. Put it back in and no more problems.
