Code P0973 Saturn Description

The Powertrain Control Module (PCM) controls the ground signal for shift solenoid 'A' to control the solenoid ON or OFF, according to transaxle and vehicle operation. When the solenoid is OFF, filtered line pressure to the solenoid is exhausted. When energized (ON), the exhaust port is blocked, stopping the exhaust of line pressure through the solenoid. Pressure on the end of the 1-2 shift valve moves the valve against the spring force, sending line pressure into the solenoid 'A' passage to the 3-4 shift valve.
