I had noise that sounded like loose valves but it turned out to be a bad timing chain.

I hear a noise coming from the transmission that sounds like VERY loose valves . But it doesn't sound like it is coming from the top end . It getts louder and faster as the engine is revved up . Does anyone have any suggestions ? One quick question , there is only one oil place that uses the oil for the engine and transmission correct ? I know the "engine" oil is full but am questioning if there is trans. oil somewhere.
Any ideas ?
Thanks,
D.
