Its a Jeep sorry you got one of them things. Let us know when it become a Heep instead. I've owned 2 Grand Cherokees, both of them were 1st gen ZJ's though back when the I6 was still available, and still had a manually shifted transfer case, yep with low range which hardly got used LOL. Don't know much about the newer ones, other than now you can't get them with the V8 which would be the only way I would have gotten another Grand Cherokee. My 1st Grand Cherokee was a Limited 4L I6 with quadra-trac 4WD, went everywhere I wanted to go, sold it with 232k on it. My 98 Grand Cherokee was the SE, basically the same thing as a Limited without the Limited stickers, also with the 4L I6 but had selec-trac 4WD. Selec-Trac was the better 4WD system both full and part time 4WD in 1 transfer case, and no electronics controlling it. I ended up trading it in with 147k on it because the transmission had issues...common to the 42RE transmission, and the engine bottom end sounded like it would grenade itself at anytime....traded it in on my 08 Ford Explorer...which was probably a good move since I now need to tow around 5500lbs occasionally.
Still the Grand Cherokee is the best all around bad weather vehicle out there I think when it comes to the 4WD systems.
Something you might want if your Jeep didn't come with it is the original build sheet (not the window sticker)...this sheet tells you everything about the vehicle...just enter your VIN on this site and print it out:
