am new to my 13 Tahoe and just wrapped a 600 mile drive down south.. Outside air temp was 97 degrees most of the day.. After stopping for a while with the truck idling when I went driving again I noticed a completely different shift pattern and what seem to be elongated v4 mode.. anyone have any idea if there’s some kind of hot operation mode that the truck goes in in order to cool off
