i just bought my first subaru about a month ago, when i test drove the car the transmission shifted great, then it quickly went down hill and started shifting really hard between 1st and 2nd, and 2nd and 3rd, past that its great. So i tried changing the ATF, changing the ATF filter, and adding Lucas Stop-Slip. Still shifting really hard. I could really use some help if anyone else has an idea.
