This may be a fault with the gear selection switch on the column itself.If this switch fails or acts up internally it can cause an issue like this here.Below is a picture of this switch.
I would start with having the fault codes checked in all computers using a scan tool or computer that will plug into your vehicle and read all codes.Once this has been done any codes set will need to be diagnosed to locate and repair the fault here.

Looking at the codes you have this sounds like the common fault of the anti lock brake hydraulic/control unit (DSC).If this is failing it will cause all of these codes to set and can prevent proper shifting like you have here.This can be a common failure and requires replacement when it does fail.
One of the other common issues is a failing valve body in the transmission itself.Usually the codes point to a faulty anti lock brake unit but valve body failure is common as well.It may be a more in depth fault in the transmission as well to where it may need removed and taken apart for inspection and repair.
Your welcome.Let me know if you need anything else and feel free to rate my help.
Unfortunately I am not to familiar on this transmissions internal components myself.I will have to open your question up for others here to see if anyone else can assist better.I hope you can get this resolved with ease.
The only other components I can see that will cause a fault like this here is a computer fault that controls the transmission needing replaced or with the previous codes the the anti lock hydraulic/electronic control unit (DSC) itself.Since you have codes for the DSC I would start with this.
That is tough to say for sure from here,it may be if they appear to be damaged or burned.
