Thanks again everyone with the replies,
I am in the process of getting into contact with Subaru.
I got my car back and it feels great with the new transmission.
Unfortunately I noticed on my invoice that the technician damaged 2 ball joints and they also replaced them while the car was being worked on. I immediately noticed that I seem to have lost some power steering.
Is it possible that the power steering was damaged while the transmission was being worked on? I do not know know much about cars and am not sure if the two are related.
