No big deal. However, by changing the fluid once these particlaes are in place it can wash them away from the detergants in the new fluid. Especially if you flush the tranny with a pump
Those of you that do your own maintenace. By droping the pan and changing the fluid and filter you have accomplished almost nothing. The TC hold more fluid than the pan does in most cases and with the pump not running "car off" there is no way to get the rest of it out. Now you are mixing old fluid with new.

I have a shop do tranny flushes. You have to be careful that the right equipment is used. You don't want one that forces the fluid through the system. You want one that uses the cars pump to cycle the fluid. This is the best, most complete, and safest way to flush the system with new fluid.
