Speedometer Operation Affected and Poor Transmission Shift Quality on Ford Tempo

The vehicle may lose vehicle speed signal, which can affect speedometer operation and transmission shift quality. Most often the Vehicle Speed Sensor is faulty, however, at times, the driven gear inside the transmission is at fault. Replace the Vehicle Speed sensor and inspect the driven gear upon sensor removal.
