I just purchased a mercedes 1994 sl600 in Phoenix. I drove it home, 1300 miles

What is your question?

to Lawrence Kansas with no problems or leaks. I then had all of the fluids replaced (car had 31,000 certified miles on it). After one day a large tranny fluid leak showed up on the floor. The dealer had changed the fluid, filter and pan gasket. They want me to bring the car in for a check up. What can I expect?
