Depending on the type of vehicle you have and how the speedometer is actuated is going to be different. You may have a speed sensor in the transmission and run off of the out put shaft or a sensor in the rear axle. Both of the sensors are known to cause erratic reading on the speedometer. The speedometer is not know to fail very often. I would recommend having the speedometer checked by a mechanic like one from YourMechanic that can come to you and test the computer to see if the speedometer is getting a jumping or no signal from the speed sensor. If loss of input then replace the speed sensor.
