Vibrating in 6th GT Jtd

Hi all - any help diagnosing this would be appreciated...

At motorway speeds in 6th, from time to time the cabin is filled with a drone/rumble/vibration. Sometimes pretty loud.

Only seems to be when in 6th. If I dip the clutch and put it into neutral (coasting at 70) smoothness resumes.

The odd thing is that when this noise/vibration occurs, if I put the car into neutral (at 70mph) and then straight back into gear, this often (not always) makes the noise/vibration disappear too..

Car has had a recent new clutch and new DM flywheel as well as a replacement low mileage gearbox

Any ideas?
