open or limited slip

[OR VietVet]

And to confirm, the G80 is a centrifugally activated mechanical locker, not a limited slip, so it does *not* use LSD additive.

What ev's.....

This is what I understood as well. It's a locker, not as LSD.

But I know guys call the G80 anything but a locker: LSD, positraction, etc.

Probably the confusion is that G80 was also a rpo code for an actual LSD on other vehicles, such as tbe F body's

I run Amsoil in my G80s with zero issues...no additive needed with the G80. 12 years in my 01 and over 1 year in my 08.

Well they pretty much all do. I was doing some research yesterday and the Valvoline brand does too. So I’m assuming it doesn’t matter. I wanted to use Amsoil or Valvoline only so I I’m just gonna use one of them with no additive because according to the bottles they already come with it.

Yep, it covers all the bases, locker and limited slip.

One more question guys. Transfer case question. I’m also going to change that fluid but I’m a bit confused. My OM says to use manual transmission fluid but I’ve read that people are using Dexron 6.

Depends on the TC. Many of them do call for ATF in the OM. Use whatever the manual calls for.

our awd 07 Yukon Denali has a BW4485 transfer case (rpo code NR3), and takes/holds 3 pints atf.
