After driving less than a mile the spedometer will start to jump all over the place. Since the transmission shift points are dictated by the speedo reading the transmission jumps from 3rd gear to 1st gear and back to 3rd -all over the place. I have replaced the VSS (Vehicle Speed Sensor) three times. Twice with an aftermarket sensor and last time with an OEM sensor. The ABS and brake lights also come on. There are no codes at least the check engine light is not on.
