Citroen Nemo Robotised transmission

[Alben]

Hi,
My Citroen Nemo 1.3 HDi 2013 shows these codes P2917-71, P2914-78, P1818-73, P1772-64 and symptoms are : It shows N all the time not any forward gear and doesn't move forward but it shows R and moves backwards.
The gearbox hydraulic has enough fluid and the pump works.
After few days trying to fix I took off a pump jack and back in, sensor jack off and in but now the car doesn't start, it does beep beep when I turn ignition off meaning that switch the gearbox to N, right.
Should I buy a gear shift actuator or what ?

Any help here please ?

Best regards
Alben

I do not know anything about auto gearboxes so can not help with that but you need to list the definitions of the fault codes to help others understand the problem and provide help.
