Was just about to check on Subaruforester.org for you but Mark beat me to it.
It is quite a good box and you can stir it up pretty good manually, not too bad on the manual downshifts unless you are going to over-rev it and it wont shift down until the revs are lower.
My lass runs it in D all day long, I never ever run in D - always up and down the box manually and had no problems so far.
