So I'm in the process of replacing my steering box and powersteering pump on my 85 F-250. My questions is my 86 calls for type F atf in the powersteering, but my brothers 97 F-250 calls for Mercon atf. I'm just wondering if one is better than the other or if it even matters since everything is going to be drained down and flushed.
