My 2004 Jetta won’t go into reverse.

What is your question?

I recently bought a 2004 Jetta with 172,000 miles. There were no problems when I tried it out. Right afterwards I had to have leg surgery and haven’t been able to drive, so the car sat in the garage for 3 months. Now I can’t get it into reverse. Yesterday I added transmission fluid with no luck. The other gears are fine and there are no noises or leaks.
