GM MT fluid does have some mystical allure... Some of the Honda guys swear by it for their manual boxes. I can look up why...That is what I figure will be my eventual go-to. NV4500 was recommended to use AC Delco GL-4 75W-85, which has a GM part number, that is now obsolete. I was lucky to scrounge the last that my local GM dealer had and a few more on eBay to use in both the trans and t-case. The Redline looks to be the replacement.
