Torsen T2 differentials are all gear driven.
Differentials that use it are usually Clutch type limited slip.
I changed the transmission and differential oil in my FRS a week after I bought it. The motul gear 300 did make a difference for cold driving. I never had any complaints when the transmission was at operating temp
I never had the chattering problem but I only had the factory oil in for a week.

You're right about how they work however the fluid that is associated with the clutches in differentials is separate. Which is why that style of diffs is not very popular among the used market... You can't change or replace it. Sucks. Otherwise I'd already have an na miata...
