So I want to change the differential fluid in my 04. I have a partial print out of what it has. It states it has the G80 positraction limited slip diff with the GT4 3.73 gears. So I'd need to know do I add a friction modifier to the fluid? Or is their a brand I should use? I'm reading some say yes and some say no. I even found some web sites that say the G80 is a locking differential, which I know it's not.
What type of fluid should I use? Also, do I need a gasket or just use some RTV?
Thanks
Edit, to make things worse. I called 4 dealers close to me. They said that it's both a locker and posi track!!!! 2 of them said I need to add a friction modifier and 2 of them said I don't. Go figure. I gave me a p/n of 88900401 and said that's what they use.
