I have an 18 STI that I bought new in July and I need help with the transmission fluid. From the beginning in the cold or when the car sat for a day or 2 it would be hard to get out of first gear and as the weather started to get colder it got worse. I thought ok maybe ill try the motul gear 300 that everyone raves about. Now its even worse then the factory fill and sometimes I cant get it into gear while driving slowly. I have tried double clutching and rev matching which help some. Thinking about going back to the subaru gear oil or maybe trying something else. It does improve after a mile or 2 but I never had a manual transmission car so stubborn. Even old cars that were beat to death shifted better than this thing.
