Default 2nd gear shifting

Hello, all! Newbie here and BY FAR not a gear head. As my dad would say about his knowledge of car repair, “I know just enough to be dangerous”. Anyways, I have a 2003 Yukon with a 5.3 engine and 119,000 miles. I’ve noticed recently that when it shifts from 1st to 2nd Gear it shifts a little tougher than other gears and there’s a “clunk” noise when it does. It also seems that the slower I accelerate the louder or more noticeable the “clunk” is. I just had the transmission serviced last August (I pull a bass boat all spring, summer and fall with it) so it’s not like I’ve neglected service on it. I’m afraid of what the diagnosis would be at the mechanic so I thought I’d stop here first to see if any of you smart, educated people would give me your .02 worth. Thanks in advance!!!
