I just had my tranny flushed and a new filter put in. When i was driving home from the transmission shop i noticed a wine when starting to accelarate. I brought it back to the shop and the guy said he did not hear anything. But he did say it might be because the new fluid did not cycle through yet. Anyone ever have this problem or have any idea what it might be. And it only makes this noise in the 2 to 3 thousand RPM range
