I have 45k on my limited wrx wagon with some mods. When i shift from 3rd to 4th at a high rpm i get a loud grind. If i shift at a low rpm and slow it is fine. Do you guys think i should start with the tranny fluid in this case as well?

The always popular 4th gear grind thread !

Yes, changing the fluid usually that issue 90% of the time. I have used the "uncle scotty's" blend with success for years, but there has been some speculation that it has downsides. Give your issue a search here and some of the other forums, and change that fluid. It will also make getting into first a lot smoother too.
