I have an '03 vw Passat . About 4 months ago I noticed it had started hesitating when trying to back uphill. I took it to the dealership and they put transmission fluid in it. It was ok for a short period of time and it started again. I took it back. They scanned it and said there were no leaks but they put in more transmission fluid. That lasted 1 1/2 weeks. They are now ordering a whole new transmission because the slipping did it when the service people drove it. They had not test driven it the previous times until after they put in fluid.
