I need help. New to forums but it seems to be that I need your f1 mod Done on my 2005 legacy gt wagon. I've done quite a bit of mods to reach what I believe is full stage 2. After mod ding through a shop called pacific im port auto in tacoma I picked up my car slipping in 5th gear and shifty shifting. They said they didn't 2 or on the transmission so they said that I needed to replace it. I replaced it and found the new one did the exactly same thing. Frustrating by the way. After research in and talking to a couple better shops it seemus that I don't have enough line pressure and that your f1 mod will fix it. I'm ready.
