Is that some sort of stock reply? Lol, if you see above I said "GM" recommends this and that, etc. thank you for your concern.
After having the system flushed and refilled with Dextron (I forget the number), it sounds good this morning. However, when I had the rack replaced, it sounded good for a while as well.
So, I am cautiously optimistic. I love this car, I just don't want to be annoyed by it every 3 months.
