What (and when) did she spill in the center console?
That would be my first guess. If not then check for codes, see what comes up.
Depending on codes, raise the car and check the connector mentioned in the DIY sticky, if it's got fluid in it hie down to the dealer and pick up the new and improved one, and don't forget the O-ring. Disconnect the battery and replace the transmission connector, cleaning out as much of the harness as you reasonably can (maybe spray some electrical contact cleaner up in there), then open the center console and remove the TCM. Clean it up with electrical contact cleaner, then let it dry thoroughly and reassemble. Reconnect the battery, start it up and see what you have. You'll have to check the fluid level so you'll need a dipstick tool, you can get that at the dealer when you're there.
If your trans connector has no fluid in it, then pop the console anyway to clean up whatever was spilled in it. I think it's honestly the dumbest design on late-model benz to put such a sensitive thing right there.
Now, if your wife promises on her vows that neither she, nor your kids, nor any of her friends spilled anything in there (and the sunroof was not left open during a gentle shower) and the connector is dry, try a battery reset. Sometimes that reboots the ECU, which is occasionally necessary on these computers-on-wheels.
Your worst case scenario is that the extended service interval of the previously-named "lifetime fluid" has claimed another victim, but my fingers are crossed against that one.
Post back and keep us in the loop!
Take care and enjoy the ride,
