Rough shifting between gears... Actually got stuck in second. had to pull over put in park to reset it. Have had quite a few problems with the transmission and the car repair shop tells me everything is fine and that I just don't know how to drive and I am probably putting the car in manual. Even with the check engine light on they claim they find nothing wrong with the car. I don't want to die in an accident due to unexpected down shifting or something
