The CVT has a similar style drain plug for the front differential, but according to a diagram in the 2010 Outback FSM, it's placed differently on the case. The whole transmission case, from the bell housing back, is new. I couldn't verify if it uses the . . .090 gasket using on-line catalogues, and the service manual doesn't even have information on changing the front differential gear oil on the CVT -- in fact, it doesn't have a dipstick for either the front differential or the transmission itself. The 2010 Outback FSM does, however, show the torque spec for that front differential drain plug at 70 N-m.
For the 5EAT, which is still used in the 2010+ with the 6-cylinder engine, the instructions for changing the front differential gear oil don't refer to different gaskets; there's only the one 70 N-m spec. But for the 6-speed manual transmission, the same three specs (44, 70, and 70 N-m) are indicated (same as for the 2010 Forester 4EAT front differential).
And going back to the 2010 Forester FSM, it lists the same 3 different gaskets for both the AT front differential and the MT drain.
Sort of interesting that Subaru refers to aluminum, copper, then metal. As if the first two aren't metal. It does, however, fit the difference between non-ferrous and ferrous materials.
I do hope that SCI will respond, but I'm becoming less optimistic as time goes on. But in the meantime it's looking more and more as if the "black" gasket in the later FSMs is the 090, with the 51 ft-lb spec, and this is being used on all the front differentials and MT drains where the 070 was used before.
By the way, in an earlier post you wrote that at 32 ft-lbs the drain plug was leaking a bit. Was this with one of the new black gaskets? I wonder if 32 isn't enough. Or has it stopped?
