I disconcur with this. My transmission shifted like arse on the factory fluid. I am sure you guys are sick of hearing about me bitch about it by now. Last month before thunderhill Nate put redline lightweight shockproof in and the difference has been night and day. The shifting is smooth, no grinds, and it is much easier to get into first now.

I understand you have had issues, but do we know the impact of having the shockproof in the diff?
I have the stock fluid in my 02, and have had no problems at all, and I slam first like nobody's business.
All I am saying is that Subaru engineers proabably spent many hours selecting te right fluid for the complete system covered by that fluid, and if it ain't broke, don't fix it.
If you are having a specific issue, talk to knowledgeable people and try something, but understand the risks involved in doing so. I personally have know idea what any fluid will do to the diff, and tranny combination in the STI.
