I changed transmission fluid, now making noises on my subaru forester X 2012

What is your question?

I changed the trans. fluid, 2 weeks ago. I did not use Subaru's trans. fluid. I can only hear the noise at slow speeds, especially when first driving the car, In drive and reverse. this happens all the time. For 2 weeks now. Should I still be driving the car ? Should I drain this fluid and filter, and put Subaru's fluid in ?

What makes this problem better or worse?

It does it all the time

How long has your 2012 Subaru Forester had this problem?
