In contrast, the transmission speed sensor monitors the output of the transmission itself. In some cases, the transmission may become stuck in a single gear, either refusing to upshift or downshift.
Transmission Speed Sensor Vs Vehicle Speed Sensor: Key Differences
The transmission control module (TCM) interprets these frequency changes to calculate the exact speed of the vehicle, which is essential for the smooth operation of the automatic transmission system. It is generally recommended to replace the sensor with a high-quality OEM or aftermarket equivalent to ensure compatibility and longevity.
How the Transmission Speed Sensor Operates The functionality of a transmission speed sensor typically involves a permanent magnet and a coil of wire, or in more modern systems, a Hall effect sensor. This movement disrupts the magnetic field, generating a voltage signal that fluctuates in frequency relative to the speed of rotation.
Transmission Speed Sensor Vs Vehicle Speed Sensor: Key Differences
Common Indicators of Failure When a transmission speed sensor begins to fail, the symptoms are often noticeable and can significantly impact vehicle safety. The sensor works in conjunction with the wheel speed sensors to calculate the vehicle speed accurately, ensuring that the gear ratios are optimized for everything from city commuting to highway cruising.
