I had same problem with my 1994 SL600. Also when this happens you will lose your interior door lights when you open the doors. My problem was solved by taking out the, A-white 40 amp 12V Relay and cleaning off the 6-prongs and reinstalling. It is located in the box underhood ahead of the main fuse box. Just need a phillips screwdriver. It is the fartherest relay in back left. I had to pull the one out in front of it to be able to remove the white one. You can hear it click when you push in dooropen switch. When working right you do not hear it. Hope this helps.

SOURCE: How do I unlock the shifter on a 2000 Mercedes

No you do NOT need a new transmission.
This model Mercedes uses an electronic solenoid in the shift housing, to take the linkage out of park.
There is a small plastic part, activated by a solenoid that pushes a release, allowing the shifter to come out of park. Most of the parts in the box were metal. This particular part is plastic and very frail.
It is not an easy job, but any mechanic can do it.

It's not that unusual for a battery to fail that soon, and the "no lights, no nothing" says that it's the battery again. Your best bet at this point is to pull the battery and take it to the point of purchase for testing. They should either replace it under warranty or charge it for you. After you replace the battery you should have the charging/electrical system checked for possible shorts or power drains.
