If it was truely flushed then you generally did a good thing...as long as the valve body is not worn out!!!!!
Before I had min flused I did a drain and refill 3 times to try and clear the old fluid out. Even after I did this, I then went to have a power flush done and their was a good portion of the fluid that was very dark! Of course I power flushed after I installed the Shift correction kit.
