4WD vehicles: Replace fluid @ 30 months or 30,000 miles.

 

"When the vehicle is frequently operated under severe conditions, replacement should be performed every 15,000 miles."

 

I'd say they know what they are talking about. They built them. Probably with tight tolerences too.

Edit: "Oil capacity: 6.9 US qt"

"When replacing ATF, the normal refilling capacity is about 2.6 to 3.2 US qt"

 

This is just removing the drain plug, and you obviously can't change all the fluid in a drain and fill.

 

The "filter" in the trans is called a "oil strainer" by Subaru, btw.

 

This strainer is how it used to be done, before desposeible came along. Clean and reuse.

So how many Quarts for a 3at?

Hey,

 

Total capacity: FWD>6.6 qts

4WD>6.9 qts

 

If you remove the pan and strainer/filter, and let it sit and drip, you can add more.

 

I'd guess close to 4 quarts doing it like that. Mabie a little more.
