2002 Chevy Avalanche Transmission shift 1st to 2nd issue?

I have a 2002 Chevy Avalanche that has 128k miles on it. In the past few weeks ive noticed that anytime the truck is shifting from 1st to 2nd gear it makes a clunk noise. All other shifts are good going up and downshifting is just fine as well. Is this something that I need to get looked at or what is it?? I dont check my transmission fluid cuz I dont have leaks or nor do I have any idiot lights going off about it. Please help me resolve this issue. Thanks.

    There could be an issue with the transmission internally, or it could be a controller issue.

    Check your fluid and see if it is discoloured or not. Just because you do not see a leak does not mean you should not periodically check fluid levels.
