The TSB for this noise is for the 2002, not the 2003. I had the same problem, and it appeared to me that the noise was on the excessive side. I could hear it click in and out anytime I pressed the brake and was going under 10 MPH, even with the radio turned up. I brought it to the dealer, the service guy listened to the noise in my car, and then we went to another 2003 on the lot and the noise was practically inaudible. They ended up replacing the entire shifter, and the noise is now gone. Seems to me that the issue they had with the 2002 hasn't quite been fixed in all the 2003's. Maybe some of the original 2002 shifters made it in to some of the 2003s at the factory.
