P0976 CHEVROLET MeaningThe Powertrain Control Module (PCM) controls the ground signal for shift solenoid B 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, and directing it into the solenoid B passage. Solenoid B fluid pressure is then fed to the 4-3 manual downshift valve and the 3-2 manual downshift valve.
