Transmission Position Sensor (Switch) Replacement
Car won’t start in Park or Neutral, reverse lights not coming on, or incorrect gear showing on the dashboard? A transmission position sensor replacement restores reliable starting and precise gear detection.This sensor feeds critical digital positioning data to the Engine Control Unit (ECU) and Transmission Control Module (TCM), while simultaneously controlling starter relay engagement and reverse light activation. As a safety protocol, it permits the starter motor to crank the engine only when the shift lever is locked safely in Park or Neutral.
