Troubleshooting Truck Transmission Woes: Signs, Solutions, and Pro Tips

Truck owners experiencing shifting issues with their GMC might have a faulty transmission range switch (TRS), a crucial sensor that communicates gear selections to the truck's computer. Symptoms of a bad TRS include getting stuck in Park or Neutral, erratic gear shifts, trouble starting, and an illuminated Check Engine Light. Diagnosing a faulty TRS involves reading sensor data and error codes with a scan tool, while replacement varies by vehicle. When towing heavy loads in a Ford truck, using the correct synthetic blend transmission fluid is vital for performance and longevity. Transmission additives marketed as quick fixes should be used cautiously; while they can address minor issues, they may also cause problems by dislodging debris that clogs the transmission. Consultation with a transmission specialist is recommended before using such additives. For those requiring a transmission rebuild, Truck Transmission Specialists aim for a one-day turnaround, keeping customers informed throughout the process. Contact them for expert transmission services for Ford, Dodge, GMC, or Chevy trucks to ensure safe and efficient road readiness.

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

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.
