Gearbox Speed Sensor

The HELLA gearbox speed sensor is a reliable component for modern automatic transmissions. It precisely measures the rotational speed of the gears inside the transmission and provides real-time data to the engine control unit or transmission control unit. This supports smooth gear shifting, efficient transmission control and improved vehicle diagnostics.

 

Thanks to contactless measurement based on magnetic sensor technology, the sensor operates with minimal wear and requires no maintenance. It is designed to withstand high rotational speeds, temperature fluctuations and demanding operating conditions. As a result, the gearbox speed sensor helps improve driving comfort, efficiency and reliability within the vehicle’s powertrain system.

Product Advantages

  • Measures rotational speed of gears inside the transmission and delivers precise real-time gear speed data for optimal transmission control
  • Contactless sensing ensures long-lasting, maintenance-free performance
  • Operates reliably under extreme temperatures and high-speed conditions
  • Seamlessly integrates with ECU / TCU for smooth gear shifts and diagnostics
