Ticking Noise Coming From Transmission Driving Me Crazy

I just recently had a similar experience with a transmission noise. When does it make the noise?
Does it do it in park, or any other gear? Does it ever go away?
The problem that I had turned out to be a bad torque converter. Something let go inside. But it only made the noise in park.
Try to diagnose the problem a little more if you can. Does it do it in the driveway or only on the road?
Any info that you can give will be a big help.
