Speedometer does not function properly. needle
A faulty vehicle speed sensor will cause this.
It's mounted on the back end of the transmission where the drive shaft slides into, near the top, it's just held in with a bolt, on the right side of the tranny, also has a wire connection.
Needle sticking or not reading correct speed
Speedometer cluster is defective. Many GM oproducts used stepper motors in the speedometer cluster. speedometer, gas gauge, tachometer etc what ever is a movement indicator.
Do not purchase a used one or one that is "repaired" if the stepper motors are not replaced with motors made after 2005. repaired units cost a few hundred dollars. individule stepper motors can be purchased on EBay for less than $10.00 each. The cluster must be removed from the vehicle and dismantled carefully, knowing it is electrical device and may be damaged by static electricity. good luck!!
