2 speed transfer case

Well I thought about that but I didn’t want to show any interest in it till I knew exactly what it was. Trying to not be aggravated by someone trying to sell me something I don’t want. My best friend is a tech at my local Gm dealer. If I had the vin I could get him to tell me. I appreciate that link for future references!!

If it's a dealership - on a Sunday when no one is there get a pic of the VIN from the DS lower windshield.

@Tonyc If you can get the VIN... I looked my VIN up at this link and one of the tabs had the correct diff ratio. Lots more info than the generic VIN lookups.
