My 95 f250 w/powerstroke diesel auto trans sounds like it has an air leak when I accelerate lightly. It goes away when I give it gas/accelerate. It also does it when in park. Could this be a torque convertor going bad?

 

Thats a tough one to diagnose from the net...If it sounds like an air leak it probably is a leak...

T/C usually rattle when they are bad..
