2. Automatic transmission pressure regulating valve 7 (N443)

3. Automatic transmission pressure regulating valve 6 (N371)

4. Transmission output speed sensor (G195)

5. Automatic transmission pressure regulating valve 3 (N217)

6. Automatic transmission pressure regulating valve 5 (N233)

7. Automatic transmission pressure regulating valve 2 (N216)

8. Automatic transmission pressure regulating valve 4 (N218)

9. Automatic transmission pressure regulating valve 1 (N215)


Mechatronic, Transmission Control Module (J217) , Sensor and Pressure Regulating Valves - Part 2






1. Parking lock solenoid (N486)

2. Transmission input speed sensor (G182)

3. Transmission control module (J217)

4. Transmission fluid temperature sensor (G93)

5. Parking lock sensor (G747)


• On Board Diagnostic (OBD) checks all the components named.
