I do have a tiptronic.  Is this a common problem?  How hard to replace?
I've never heard of this.  Could it be low on trans fluid causing this?
I just recently had a new torque convertor put in and it shifts fine but
maybe the fluid is low.  I haven't checked it.

If you have a tiptronic its probably the air pump that you're hearing. 
Manual's don't have them. It only runs for a short time after a cold
