The Final Drive Ratios, and Transfer Ratios make ALL the difference between nuking the diff and trans or not. I've literally seen rear diffs catch fire from wrong transmissions swapped in.

The Gear set ratios make no difference.

Also- Variations in if the trans has Vehicle Speed Sensor, (VSS) nor not. '08-and later went to ABS, no sensor in the trans.

Variations in Front axles Female (roll pin style Usually '04 and earlier) or Male (clip in) axle interface.

Here's the chart with the Trans codes

Bottom of the list you should have a TY754VC7AA , 3.900 FINAL, with a 1.000, Transfer = Only other on the list similar would be 05-07 LEGACY, {forester and outback WILL NOT WORK UNLESS swapped with the matching Rear Diff assembly.}
