Transmission and Differential oils

[Nodzed]

Gulf Competition 75w 140 for the diff and Fuchs Titan ATF 5005 gearbox, as recommended by Opie for the M (though I used Castrol Syntax in the 2.8)

Not my photo, but it will help you with your diff identification.

Well, after digging into mine a little further, it is a typical clutch LSD. I was reading elsewhere that the "R" on the tag meant Torsen, but not the case here. I tore mine apart and the friction plates are as smooth as glass which is why it was acting as an open carrier.

The oiling holes on the 168mm small case LSD look a little different than the one in the 188mm case as pictured a couple of times in this thread.

Am I right in thinking that all 3.0 have the same diff? And

When I did my LSD I used Castrol Syntrax Limited Slip 75W 140 :

Would be suitable for it? What about gearbox oil?
