Mastering Your Truck's Gears: Troubleshoot and Replace Your Transmission Range Sensor

Tyler Spangler

Published on: 11/04/2025

If 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.

Master the Fix: Resetting Your Truck's Transmission Control Module (TCM) Made Easy

Tyler Spangler

Published on: 15/02/2025

If you're experiencing rough shifting or error codes on your truck's dashboard, resetting the Transmission Control Module (TCM) might help. This process requires an OBD-II scanner, safety gear, and your owner's manual. Generally, you need to disconnect the battery's negative terminal for 10-15 minutes for a PCM reset and use the OBD-II scanner to reset the TCM. Procedures can vary, so consult your manual. Notably, a TCM reset doesn't address underlying issues, and it's wise to refer to Technical Service Bulletins (TSBs) for known problems. For in-depth problems or professional resets, visit authorized dealerships. For expert help, Truck Transmission Specialists, led by Luke Harrison and Tyler Spangler, offer superior transmission repair and upgrades. Contact them for personalized support.

Unlock Your Truck's Potential: A Beginner's Guide to Adjusting Transmission Shift Points

Tyler Spangler

Published on: 12/11/2024

Adjusting your truck's transmission shift points can significantly enhance its performance by optimizing it for fuel efficiency, towing power, or a sportier driving experience. Shift points are the engine speeds (RPMs) at which the transmission changes gears, controlled by the Transmission Control Module (TCM). Adjusting these points can allow your engine to run more efficiently by operating at lower RPMs for longer, provide more power and torque for heavy loads at lower speeds, or deliver quicker acceleration for a more responsive drive. The process involves locating the TCM, identifying current shift point settings, and making small, incremental adjustments using a scan tool or following procedures in your owner's manual. It's crucial to make minor adjustments and test drive after each change while consulting the owner's manual for specific instructions and warnings. If unsure, seek professional help to avoid potential damage, with the experts at TTS available for guidance and assistance.
