Code P0973 Description

The P0973 diagnostic trouble code (DTC) refers to a Shift Solenoid 'A' Control Circuit Low. This code indicates that there is an issue with the electrical circuit that controls the shift solenoid 'A' in the transmission. The shift solenoid is responsible for regulating the flow of transmission fluid to engage the appropriate gear for optimal performance. When the control circuit is detected to be low, it means that there is a problem with the electrical signal that controls the solenoid, which can lead to improper shifting or failure to shift altogether.
