Hi my freelancer 2 14 plate has a vibration when in 6th gear at 50mph it clears at 55mph it's as if it's not ready for top gear, it's the same when in 5th doing 40mph then clears at 45mph. It used to be smooth at they speeds. I'm thinking fuel filter? Any ideas?

I wouldn't have thought fuel filter. Has this only just started happening? Are you saying that the vibration is at the same rev range in both instances? Is it engine speed related? What happens in 3rd etc. Mine has to be at just over 50 in 6th before it feels comfortable and I often think that the green "change up" light is coming on too early. 3 x FL1 2 manual + 1 auto
