Also known as the turbine shaft speed sensor, the speed sensor in a transmission is a magnetic coil that provides a vehicle's control unit with the rotational speed of the torque converter or the input shaft. This information is used to allow the vehicle to shift smoothly and run efficiently.
Although symptoms of a failing turbine shaft speed sensor vary depending on the model and year of the vehicle, common indications include a dead cruise control system, an unresponsive speedometer or odometer and an inability to shift correctly. A failing transmission speed sensor may also affect the vehicle's fuel consumption.Learn More
When problems occur with the speed sensor, the vehicle does not send the right signal to the speedometer, regulate fuel properly, operate cruise control or regulate ignition timing correctly. Problems with the speed sensor are the result of wear and tear and have a direct effect on the performance of multiple systems in the vehicle. The most common symptom of a malfunctioning speed sensor is a malfunctioning speedometer.Full Answer >
A transmission range sensor, or TRS, sometimes referred to as a neutral safety switch, is a safety device and sensor that, when faulty, prevents the car from starting unless it is in neutral or park. Failure of this part is generally common among older, high-mileage vehicles as the sensor becomes exposed to the weather and various elements.Full Answer >
A bad speed sensor most often affects the shifting of the automatic transmission. However, in cars with an onboard computer, the sensor also affects the ABS system, speedometer, cruise control and power steering. Proper diagnosis and repair is essential for safe operation of the car.Full Answer >
The torque converter is located near the car's engine. The part has four main components – the pump, the turbine, the stator and the transmission fluid – which are connected to various parts of the engine.Full Answer >
