It seems as if the vehicle speed sensor may have a malfunction. The vehicle speed sensor is typically mounted externally to the transmission. This sensor sends a signal to the powertrain control module which then sends a signal to your gauge cluster. The gauge cluster will then display the RPMs of the engine and the speed of the vehicle. I would recommend having the sensor tested by a qualified professional to determine its Integrity. If the sensor is faulty I would recommend having it replaced in order to resolve the issues you are having.
