t56 noise
The only other possibility I could think of in this case would be the bearing between the input and the mainshaft. If that's the case, then it should be quiet in 4th gear since the input and the mainshaft are both turning the exact same speed. (1:1) The cluster turns at all times too so I doubt that's it or it would make some sort of noise all the time.
