The manual calls for GM Part # 12378396. A tag on the TC says NP 236, and a seperate tag calls for the same product to be used in the transfer case. That part number is Dexron lll. The TC has a manufacture date of 1998. The vehicle went into service in Oct. 1998. I have to assume this is the original TC. I used GM part no. 12375808. I can't put my finger on an official document from GM saying I should have done this, but everything I've heard or read indicates that these TC's need to have this fluid in them. I think the point of this whole discussion is that if your automatic transfer case does not have this improved fluid in it you should get it in ASAP. I've read Bulletins calling for this fluid exchange on Asrtos, Caddies, Bravadas and other vehicles from model year 1999 to 2003. I think I've done the right thing. MT do you agree?
