Transmission chirp when shifting from 4th to 3rd

What is your question?

Good morning I hope y’all have a great Christmas. I have a question I just had a 6l80 put in my 2015 GMC Sierra 1500 5.3 4x4. Every once and awhile when I’m going around 40 MPH and I tip into the gas and it has to shift from 4th to 3rd it will make a chirp sound. It doesn’t do it when I am braking and it shifts from 4th to 3rd only when getting on the gas. Not every time but maybe 50 percent of the time. It shifts great is this something I should worry about?
