I own a 2003 Tahoe Z71.

There was a harsh engagement when shifting at usually a low speed when going from 2nd to 3rd around 22 MPH. When I would rapidly accelarate say from a stop to 35 MPH there was no noise only when done slowly as I don't like to Jack Rabbit. It would also occur much more intermittantly when rapidly decelerating from a higher speed at again 3 to 2nd approx.

I brought the car to the dealor for a test drive and he acknowledged a noticeable noise. He said there was a service bulletin and they address the problem. They explained as the way the Computer was communicating with the Transmission. My take in laymans terms they would essentially recalibrate the computer?

Anyways I get the car back from the dealor and it's worse. The noise maybe isn't as loud but it happens far more often at much more varying levels of noise but on a less predictable basis. Very very annoying. Only 15k miles and I've never towed anything.

I've since found there may up to 3 service bulletins. Any suggestions?
