My trans has been making this metallic jittering clatter sound for a while and sounds like a can of marbles in neutral when fully warmed up, Zero issues shifting(other than shifts being kinda notchy i guess?) or anything other than the noise which is loudest in 4th gear. I just had the clutch done and transmission serviced about 3500 miles ago and i’m wondering if my trans might be cooked.
