Hi few weeks ago my garage change partially (only 5.5 liter) oil in my zf6 gearbox , because of some harshness and juddering I am considering one more oil change using ravenol atf6 hp fluid which is verified by audi and BMW owners as a as good as Zf fluid ...and dedicated to Zf gearbox .
Should I consider buying new filter or using already mounted is possible(As I said its mounted new 2-3 weeks ago )?
