Stop in for a cup of coffee

I do see a little metal in the pan. But I have seen that before, and after fluid change, trans was ok. Might consider an aftermarket drain plug with a magnet on it. Also your original filter does not look like your replacement. But the replacement is correct, has larger filtering mass..

I remember the first test engine oil filter I cut and inspected at work. I was very concerned. I asked the Director of Develoment about it, he asked..."have you ever cut a filter on your truck?" I replied no, he said "Don't, you will be paranoid every time you go somewhere. That filter is really good for what we just did to that engine".
