I have searched this site and Castrol, Pennzoil sites and cant find the fluid to use. The manual Castrol transmax J which they dont even list. Other than Subaru brand any others that will work. The auto store said they did not know either??? thank you

Idemitsu ATF Type HP

From owner's manual:

Use one of the following types of automatic
transmission fluid.
Genuine Subaru Automatic Transmission
Fluid Type-HP
IDEMITSU ATF HP (as noted above - $9.60 a quart on Amaz.)
Castrol Transmax J
Pennzoil ATF-J*
* Available only in the USA (except
Alaska and Hawaii)

Nissan's ATF-J is also reportedly the same.

 

I think you're going to have to pony up and buy one of these...Dexron III, etc. is NOT recommended. Type-J or the Subaru HP for 5EAT transmissions.

The idemitsu is available by the case on ebay for about $6 quart. Typically I replace 3.2 quarts every third oil change or so. That is the amount that drains from the trans pan. There really is not a way to drain the complete tranny and torque convertor, so periodic maintenance with a partial atf change makes sense to me.
