Seems to change slightly better in economy mode . Changing gears manually works perfectly . I have noticed it makes a slight clunk noise sometimes when selecting a gear , does this sound normal for this type of gearbox ? should i be looking at changing gearbox oil ? what oil do i use and do i put an additive like slick 50 in to try and help ? Any reply is welcome please , thankyou Last edited: Oct 17, 2016
