I have a question for you gurus. I’m looking at acquiring a thirdtwin. The local Chevy house has a 2015 LT with 4wd. The listing says it’s a single speed transfer case. I assumed, I know right, that really meant AWD. looking at it in person the selector still has 4Hi and 4Lo.

So what is a single speed transfer case versus 2 speed?

im looking at a future overland ride upgrade from thecopcar.
First Pic is single speed transfer case knob.

Second pic is two speed transfer case knob.

Two speed has 4low

A triplet?! You're Nutz!

I'd say the listing is incorrect.
It must be a 4wd.
AWD = "1 speed"
4WD = "2 speed"

Early LT motor...Ive heard drama.
Did you test drive? Try to put it in 4Low?



I originally was looking for a white '15-'20 SSV...but at the time, they were at least $10k more for a '15 vs a '14 with the same miles.

I have not driven it. Stealership is closed today, and open Sunday. Stupid blue laws.

I have dirt roads in my neighborhood to test the 4Lo on.

Most likely theothertwin will go in trade, or be sold to a neighbor's boyfriend.

Was last night but all the same, changed my diff fluid for what might have been the first time in 135k miles. There was a solid 1/2in of metal powder/sludge on the magnet and the fluid was silvery black. Hope no permanent damage. Also added a spring pad on the drivers rear to help level it out after adding 2in drop springs.

Test it on the street...just drive straight. It'll obviously shift very different speeds as High.
I've actually never had mine is a situation where I used Low range, yet.

Ah, got you, a newer replacement.
