Code P0758 Saturn Description

The 2-3 Shift Solenoid (SS) valve controls the fluid flow acting on the 2-3 shift valves. The 2-3 SS valve is a normally-open exhaust valve that is used with the 1-2 SS valve in order to allow four different shifting combinations. The solenoid attaches to the control valve body within the transmission. The Powertrain Control Module (PCM) controls the solenoid by providing the ground path. When the Powertrain Control Module (PCM) detects a continuous open, short to ground or short to power in the 2-3 Shift Solenoid (SS) valve circuit, then Diagnostic Trouble Code (DTC) P0758 sets.
