Code P0973 Chevrolet Description

The shift solenoid 1 is part of the control solenoid valve assembly which has no serviceable parts. The shift solenoid 1 is a normally closed ON/OFF solenoid and is controlled by the Transmission Control Module through a low side driver. When the shift solenoid 1 is energized, shift solenoid 1 fluid pressure is directed to the clutch select valve 2. Power to the shift solenoid 1 is supplied by the Transmission Control Module through a high-side driver. The high-side driver protects the circuit and components from excessive current flow. If excessive current flow is detected, the high side driver will turn OFF. When the fault is corrected, the high-side driver will reset. The Diagnostic Trouble Code (DTC) will be set when the control solenoid valve assembly detects an internal low voltage electrical malfunction of the shift solenoid 1 control circuit when the shift solenoid 1 is commanded OFF for 2 seconds.
