New to me Yukon XL Denali

[BigClay]

Howdy everyone. I sold my 99 Tahoe a while ago and picked up a 04 Yukon XL Denali.

I have been searching but I can't find some simple information about it. What transmission do I have behind the 6.0? I know it is all wheel drive and is split 40/60 but don't know what the transfer case is.

Thanks for any info you can give me about this new to me Denali.

Thanks guys, and I will get some pics up soon. The difference between the 5.7 and the 6.0 is night and day. I love the power, and even though it is bigger, it sure doesn't feel like it.
