You need to know how to fix the speedometer cable if the speedometer in your Chevy Cavalier is jumping around erratically or not moving at all. While you can buy a complete replacement kit for the cable, here's a quick fix to make your speedometer work again.

Locate where the speedometer cable on your Chevy Cavalier connects to your transmission. Follow the cable from the gauge in the dash through the firewall and down to the transmission casing. All of this will be on the driver's side of the car.

Step 3

Loosen the lock nut on the speedometer cable that holds it into the transmission using a crescent wrench. Pull the cable out of the transmission.

Step 4

Wrap the end of the cable with Teflon tape. Just two layers will do the trick. Insert the cable back into the transmission and tighten the lock nut to hold it in place.

Step 5

Loosen the lock nut holding the other end of the speedometer cable in the gauge. Withdraw the cable, wrap the end with Teflon tape, replace it in the gauge and tighten the nut.
