Buzz noise

[wiser1]

Hi. I have a 2003 with a 4.8 L automatic. Yesterday it started making a buzz noise. It only lasts for a second and it only does it when I take it out of park and when I put it back in park. Any ideas?

Welcome to the Forum from NH. Longtime lurker? That's fine.

Lots of knowledgeable folks here who freely share their knowledge, experiences, and perspectives. Knowledge is power.

I hope that you will become a participating member in the Forum's discussions.

Pics of the truck, please.

Can you give us a better understanding about this buzzing noise?

Is it loud? Recordable loud?

Can you identify the general location of the buzz? Front like engine bay? Middle like in transmission/transfer case?
