So today omw to get my sister, my brake pedal started kicking back at me when im coming to a complete stop. Than that went away and 2 minutes later my trans wouldnt go into 3rd. And it wont go to 4th. A couple weeks ago I did a trans fluid and filter change because my trans barely worked at all. My abs light is on so its probably a bad speed sensor... but the trans... am I screwed? Thanks in advance
