Colder weather, hoses are cold, you probably have a vacuum leak.
Take handheld vacuum pump and test the hoses from the truck's vac pump, the booster, the vrv to transmission, Modulator, etc. Worst case scenario, replace all vac hoses and reset the VRV to spec.
Despite some well intentioned umm people saying "well thats just how a c6 works" It is not. fix the problem, your transmission will run better, and it'll live a lot longer.
Thats a pet peeve of mine.... "C6 transmission don't shift well" "Twin I beam front suspension sucks" "brake drums aren't any good" This is stuff that is said by people that are too stupid to learn how the parts work, or too cheap to replace parts that were worn out 100k miles ago.
