I use idemistsu ATF hp in mine.

It's the same stuff as the Subaru fluid for my 09-13 forester

I buy it for 33.00 for 5 quarts off amazon.

My Forester uses it both in the transmission and power steering pump.

If doing a full trans flush with a flusher machine you'll need 9 quarts.

If just a drain and fill 4-5 will work for the trans.

You'll need another quart at least for the power steering.

That is if I remember all this correctly.
