I grabbed a trans from a 02 Outback for a 01 Forester.  The forester has the old style suspension found on 90-99 Subarus Legacy's.  

 

The original trans was a 4.11 but the Outback was a 3.90.  So I had to swap the rear diffs as well.  I didn't know for sure they would fit, but all bolted up well and it's going down the road.  The new style suspension was harder to get the rear diff out, as the side play to pop the axles out was not near what the older style is.

 

Hope this helps someone down the road.

A r160 is a r160. They have the same casting throughout the ages. The internals have changed in terms of axle splines, etc. But they'll all bolt up just the same.

Change the brackets that attach to the nose of the differential and it should go right in.

 

I'd question the Outback being a 3.9, if it was a 5spd it should be 4.11 and if it's an auto it should be 4.44.

I wasn't gonna argue about that, but yea. An outback should be what you said.

I just punched in the trans code and that is what it came up with.  

 

Anyway they match now as they trans and rear diff are from the same car.  $60 for the diff and some time.
