Is there a good manual that will show the auto trans service on a 2003 Outback wagon. It looks like the filter is also replaceable. Any help would be appreciated.

What do you need to service?
The engine or the gearbox?

Honestly you'd probably be better off just taking it to a dealer to get that kind of work done. I've heard some bad stories from folks trying to do it themselves. Check over at SubaruOutback.org (http://www.subaruoutback.org) and I'm sure you'll find some answers to what you're looking for.
