I have a 2017 Chevy Colorado with v6 and 8 speed tranny. It clunks a lot at a start up from dead stop, after you get up to sped it shifts normal. It also clunks going into reverse when backing out garage. Is there a fix???

This would be better asked of your dealer or possibly look for Technical Service Bulletins.

I agree with @oldtimer-11. Your vehicle is still under warranty, keep good documentation and don’t let the dealership brush you aside. I would NOT try to do anything yourself since you’re having these kinds of problems while the vehicle is under warranty
