Take out the cluster gear, the caged roller bearings have a tendency to separate from the cage. Check the gear channel ring and fork for excessive wear.
Knocking in 3rd gear can be caused by TC, usually is caused by bad ring & pinion (rough surface) and loose carrier bearings.
Keep looking till you find the bad/worn parts.
