The P0766 code is detected when the gear required by the Engine Control Module (ECM) does not match the actual gear when driving
The Engine Control Module (ECM) uses signals from the output shaft speed sensor and input speed sensor to detect the actual gear position (1st, 2nd, 3rd or O/D gear). Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical problems of the shift solenoid valves, valve body or automatic transaxle (clutch, brake, gear, etc.).
