2015 Chevy Tahoe 4WD

We're looking hard at the 2015 Tahoes. Had a question about the 4WD modes but can't seem to get the straight answer. Felt it may be better to come ask from people that aren't employed at the dealership.

Single speed transfer case has choices to go in 2HI, Auto, and 4HI. As I understand it, 2HI is straight rear wheel drive. Auto is a computer controlled mode that will put power to the wheels that need it, and 4HI is locked-in no-kidding 4WD without "help" (interference") from the computer's traction control system.

The reason I ask is that I dislike "4WD" systems that aren't truly 4WD. I was raised with 4WD trucks and when I ask the vehicle to be 4WD, I want it 4WD...not some quasi-4WD mode that is out of my control. (Our 2004 Tahoe had the quasi-4WD and it did nothing but annoy at times.)

Thanks for any help.

    Great question. As I understand it, it is certainly a single speed transfer case, so no 4lo. It sounds as though you have it right. I don't know how sophisticated the system is, but I would imagine to save gas and wear the "auto" bridges the gap between the two by staying in 2wd until it senses the need for 4wd.
