Automatic Transmission Speed Sensor

Why This Sensor is Essential

The automatic transmission speed sensor is a key component in your vehicle’s transmission system. It monitors how fast your transmission is rotating, sending real-time data to the engine control unit (ECU). This helps ensure the vehicle shifts gears smoothly and maintains optimal fuel efficiency.

How the Sensor Works

The sensor detects the rotational speed of the transmission shaft using magnetic or hall effect technology. It then converts these measurements into electrical signals and supplies them to the vehicle’s computer. This allows the ECU to precisely manage gear shifts and maintain proper engine performance.

Consequences of a Faulty Sensor

• Erratic or harsh gear shifting
• Poor fuel economy
• Activation of the check engine light
• Possible loss of drive function
