What can I put in this thing for better low temp feeling. I'm not sure if its the stock fluid thats unimpressive or the transmission but my 11500$ 2007 focus was had amazingly better shift feel than this 2011 "premium" forester Right now it goes from "very tight" to "loose" and colder mornings are coming. any suggestions? Oh and it shares sump with the front diff so it has to be good for Front diff + MT.. some type of GL-5? I've got the initial 5000miles of breakin done so it wouldnt be a total waste of time to change now right?
