Circuit / System Description
The 2-3 shift solenoid (SS) valve controls the fluid flow acting on the 2-3 shift valves. The solenoid is a normally-open exhaust valve. With the 1-2 SS valve, the 2-3?SS valve allows 4?different shifting combinations. The solenoid attaches to the control valve body within the transmission. The 2-3?SS valve receives voltage through the ignition?1 voltage circuit. The transmission control module (TCM) controls the solenoid by providing the ground path on the 2-3?SS valve control circuit.
When the TCM detects a continuous short to voltage in the 2-3 shift solenoid valve control circuit, then DTC?P0977 sets. DTC?P0977 is a type?A DTC.
