what do these codes mean?

2002 E320 4MATIC


ENGINE MANAGEMENT
P2037 - no or incorrect CAN message from control unit N15/3 (ETC [EGS])


ELECTRONIC GEAR SELECTOR
P1817 - Voltage Value pushbutton or something


I am unable to get into the transmission
was wondering if these codes could shed some light.
Also no display of what gear i am in on the instrument panel. not even a change in pixels when i switch gears.
when i try to connect to the transmission it blinks twice displaying the gear i am in, weird.

I have replaced the 13 pin pilot bushing as it was leaking. also cleaned off the connector.
a little fluid got onto the TCM contacts. there was no fluid actually on the board itself but i sprayed it with MAF anyway. but none of this has helped me communicate with the TCM. i do have a scanner that is capable of getting into it.

How would I go about replacing the gear selector switch, and would it have any thing to do with me not being able to communicate with the TCM or are they separate problems?

Is this a pretty common thing that fails? How much does the switch cost?
