This thread is a few years old, but seems to be on topic for me. I am looking at 2024/2025 Silvarado 1500 4x4. The 2spd transfer case option is a $200 upgrade. With this selectorI can chose 2 hi, 4hi, and 4lo. Where as the Auto has 4 hi setting and Auto that kicks in as it determines. More like an adaptive AWD, than a true 4wd. If someone could clear this up for me I would appreciate it.
