whining noise on 2007 GMC Sierra 2500HD
I always enjoy coming on here and getting advice on minor bumps I come across along the way.. My current issue is on cold days only, I have a "whine" when first driving my truck until it warms up aft...

Besides, when the inside of the vehicle is warmed up, your breathe doesn't fog up or freeze on the windshield causing you not to be able to see out.
Cold tranny oil flowing thru torque converter.
Your tranny guy is right.......ignore it
And don't take it into dealership unless you want them to tell you you need a new transmission..cause you don't.
And WHY are you letting it warm up for 10 mins or so????
Totally not necessary....modern computer controlled engines don't need that wasteful warm up time.
Start it up, buckle up, check the mirrors, tune in your favorite station and drive......just don't hammer down until engine coolant temp comes up.
