My check engine light just came on last night after a quick, sudden braking. It sounds fine and is running just fine. After paying $70 bucks just to check why the light came on, I was told it is a P0773, Shift Solenoid E (Electrical Problem) which they couldn't do. What is this error? What is wrong? Where can I get this fixed?And how much will this cost me? Thanks so much everyone!
