Question Intermittent clanging noise a result of bad engine shocks/motor mounts?

Hello to everyone.

My 1983 300TD Wagon has been running great. However, over the past 6-8 weeks, it has developed a strange noise at low idle. At first I thought for sure that it was a loose heat shield some where, but I couldn't find anything. The best I can tell, it seems to be coming from right around the torque convertor, but that is a general estimation. It only makes the clanging noise btwn. 700-900 rpm's. If I'm in park or nuetral and rev it up to 1000 rpm's+, it completely goes away. I don't here it when I'm driving, only when the car comes to a stand still. It has not affected the performance of the vehicle in any way. It's just plain annoying. The other day I read a thread that suggested when motor mounts and shocks get worn out, they can act as a "short" for sound, and amplify what would otherwise be a normal running engine. Does anyone know anything about this? I have suspected that I need to replace my mounts/shocks, because the car vibrates considerably at normal idle (700 rpm's). If I rev the engine, the vibration goes away, as does the sound. So basically I'm looking for a connection btwn. the bad shocks/mounts and the sound. Any input?
