Other 4 errors are as follows
P0841 transmission fluid pressure
P0894 transmission slip
P2732 pressure control solenoid F (stuck)
P1634? Still trying to find out what this code is

Does the car even start? What symptoms do you notice as far as performance. Also have you tried clearing all the codes and see what returns? These cars throw a lot of codes over time. Most of them can be in stored / not present mode. Which means you can simply clear them. Several of the codes are transmission related. Which means you have an issue. Most likely the valve body or conductor plate. The TCU does not often go bad, but it can in rare cases. Also, it seems that you are using a generic scanner. You may need to get a scanner that's specifically for MB.
Btw, if you are loosing connection to all those modules you may have an issue with the Engine Control Unit as well. I would try to address that first before replacing any of the other parts.
