Product Features and Specifications

The SC815 sensor features a bolt mount design that allows for straightforward installation directly on the transmission mount. Its black finish and rectangular female connector provide a secure and reliable electrical connection. The sensor includes one connector with two male blade terminals, ensuring compatibility with the vehicle's wiring harness. This part does not include a wiring harness, dust shield, mounting bracket, or hardware, so these components must be sourced separately if needed.

Function and Application

This automatic transmission input shaft speed sensor is essential for monitoring the rotational speed of the input shaft in the transmission system. It helps the vehicle's transmission control module regulate shifting and maintain optimal performance.

  • Detects input shaft speed to assist in smooth gear shifting
  • Prevents transmission slipping and erratic shifting
  • Helps avoid transmission overheating by providing accurate speed data
  • Supports proper torque converter lockup timing
  • Reduces risk of transmission-related error codes and limp mode activation

Installation Notes and Tips

Installation requires removal of the old sensor from the transmission mount using the single bolt hole. Ensure the connector is fully seated and locked into place to avoid electrical issues. Since no mounting hardware or wiring harness is included, retain original components or acquire replacements as necessary. Verify compatibility with Volkswagen Golf, Golf SportWagen, and Jetta models before installation.
