The speedometer is not working properly. It might show that you are going 70 mph when in fact you are only going 50. Sometimes it goes past the 120mph. You can reset it might turning the key switch on and off until it drops to zero, and it might work properly for a day or two then go back to working improperly. I am also having a jerk in my transmission, if rapidly accelerate or not come to a full stop and accelerate. Are the two connected some how?
