What can cause a Tiptronic to bang into first gear when down shifting?

I started another thread describing a few issues that I was trying to sort out with the car (the running rough on a cold start thread). I also have an issue where the transmission bangs hard into 1st gear when I downshift as I'm rolling slowly. If I'm at a stop, it's ok and if I'm rolling faster than 5 or 6 MPH it's ok. However, it has a violent knock that feels like a bad transmission mount when I'm in between those speeds. I mentioned it in the other thread and thought that I fixed it after I changed the engine and transmission mounts (along with other stuff) because it didn't bang into first gear for a few drives after I did all that work (maybe had something to do with disconnecting the battery).
Unfortunately, after putting a few more miles on the car, it now has the same problem again! My car is a 2001 and only has about 19,000 miles on it and has been doing this since I got it with 17,500 miles. Other than this one issue, the transmission feels 100% perfect. Is this possibly normal? If not, any ideas on what it could be? I wanted to start another thread since this is a very specific problem.
Thanks!

When was the transmission last serviced?

I don't show any service in any of the paperwork.

Then change the transmission oil and filter; while you may only have low miles, the fluid is 14 years old.
