Factory fill tends to keep the trans feeling notchy. Doing your LSD at the same time is just good practice and maintenance even though the manual states a "Check" at 30K miles.
Switching to Motul, Amsoil, or Redline improves the feel and quality of both fluids.
I switched them maybe 2 weeks after getting my BRZ with 13K miles and the difference when switching gears was improved compared with the factory fill.
