Tackling Transmission Troubles: Diagnosing and Repairing Shift Solenoid Issues in Your GMC Truck
Tyler SpanglerIf your GMC truck is exhibiting symptoms like erratic shifting, hard shifting, or an illuminated transmission warning light, it may have a problematic transmission shift solenoid. Begin by checking the transmission fluid level and cleanliness, then use a scan tool to read any stored diagnostic trouble codes (DTCs) that can lead you to the faulty solenoid. Inspect the wiring and connectors for damage or loose connections and consider performing a transmission pressure test with the help of a certified mechanic. Once the faulty solenoid is identified, replace it with a new one that matches your truck's specifications, clear any DTCs with your scan tool, and test drive the truck to ensure the problem is resolved. For complex issues or professional assistance, the expert technicians at TTS, Truck Transmission Specialists, are available to provide top-notch GMC transmission repair and rebuild services.
