So... GM went from Dex3 (III) straight to Dex6 (VI)? What happened to Dex4 (IV) & Dex5 (V)?

Looking to change out my fluid & gear oil (LSD) soon...

Red LIne DIII was available meeting the older spec.

That said, I'm pretty sold on the Torco, and have Hi-Vis in the trans. I learned that Torco was producing good results in GTO LSDs, which were blowing out with a ridiculous amount of frequency..have been using it since for most trans and diff applications. And occasionally oil, thought that is a tough price point. No affiliation.
