Mastering Your Truck's Gears: Troubleshoot and Replace Your Transmission Range Sensor
Tyler SpanglerIf you're experiencing difficulty shifting gears, a refusal of your truck to start in Park, or erratic shifting patterns, these issues might point to a faulty transmission range sensor (TRS), crucial for informing the Transmission Control Module (TCM) of the selected gear to ensure smooth shifting. To diagnose the problem, perform a visual inspection for damage, a multimeter test to check voltage output, or use an OBD-II scanner for trouble codes. If a bad TRS is confirmed, replace it by first disconnecting the negative battery cable, removing the faulty sensor, installing the new one, and reconnecting the battery. A TCM reset after replacement can optimize transmission performance. If you need professional help, contact Truck Transmission Specialist for experienced diagnostic and repair services.
