P0757 PONTIAC 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. When the Powertrain Control Module (PCM) detects a 1-2-2-1 shift pattern, then the Diagnostic Trouble Code (DTC) P0757 sets.
