I'm probably missing something obvious but what benefit should I expect to gain by not referring to the clunking noise with my dealer?

Just for reference...I have the eight speed. I will find it hard to accept living with that defect on any new truck. Maybe my dealer will be more accommodating.

I have a 2015 sierra denali with the "clunk". About 1400 miles and the first I noticed it was about 200 miles. It occurs when shifting up or down at low speed with little throttle. Feels/sounds very much like u-joint but hope it isn't the differential. Haven't had to dealer yet. Has anyone solved this issue either on their own or with dealer assistance?
