So......Long story short; Took my 04 escalade 6.0 with 100k to cadillac to have the transmission, transfer case and differentials drained and filled. On the receipt it says they used P/n 19286293 which is dexron VI in the transfer case. I know from reading around that this shouldn't be used in this transfer case. Called the dealer and he assured me it is fine to use in the transfer case and refused to believe otherwise. What do you guys recommend? I am going to contact the cadillac customer service people that are frequently on this forum but am I safe driving around like so until it gets sorted out? Thanks guys.

That is the wrong fluid as they used that on the hummer h2 due to the different transfer case not sure if it will hurt it or not
Go to a different dealer and see what they say

There is a thread in the stickied DIY section from 2008 that also recommends Dexron VI for the transfer case and I know I have read elsewhere that there was a service bulletin sent out stating that GM was replacing Dexron III with VI. I just did mine not too long ago with it and I'm quite sure your vehicle will be fine. If you want to pursue trying to prove the Cadillac service engineer wrong you can, but the way I see it is if something goes wrong, and the work was done at a Cadillac dealership, you really have no worries that they will be fixing it on their dime.

Thanks guys. I don't really care to prove anyone wrong, just want to make sure my truck is going to be ok.

if you have the NP8 transfer case it takes AutoTrakII fluid
all others (NP3, NR3 & NR4) take Dexron (originally it was DexronIII but now it's DexronVI since VI supersedes III)

On my 2003 the owners manual says to use the dexron ATF in the t-case.

I went through this last year when I changed the TC fluid. I ended up using Mobil 1 ATF that says on the label that it meets DEX III-H specifications, what our TC calls for.

I have a ton of DEX VI in the garage for the transmissions but it seems I can't find any info newer than the bulletins that say not to use DEX VI in transfer cases or manual gearboxes that specify DEX III. There is even discussion on the DIY thread you pointed out that has the same discussion but no resolution. In transmissions it's a no brainer, but the TC and gearboxes are a little different beast.
