Code P0973 2014 GMC Sierra Description

The P0973 diagnostic trouble code (DTC) for a 2014 GMC Sierra indicates a problem with the Shift Solenoid Valve 1 Control Circuit having low voltage. In an automatic transmission system, shift solenoids are responsible for controlling the flow of transmission fluid to engage the appropriate gear for smooth shifting. Solenoid Valve 1 specifically manages the first gear shift. When the control circuit detects low voltage, it means that there is an issue with the electrical signal that controls the solenoid, leading to potential transmission problems.
