What does a diagnostic code 67 mean with a wrench sybol next to it ? slk230 on 1999 Mercedes-Benz SLK230

I stored my slk over the winter and when I went to take it out noticed dried what looks like transmission fluid on the floor. When I turned on the car it showed a flashing coded with a wrench symbol of 67 or 61. can I drive my car to the repair shop or should I have it towed.? NAy is help is appreciated . Thanks
