Just bought my first 'bird and I have a question. My car is a 4.6 automatic that seems to shift good from 1-2 but 2-3 seems to drops into third at really low rpms. It just seems a little strange. I don't think it's slipping, just doesn't seem normal. Could this be caused by a faulty O/D button on the shifter? I am used to GM products, this Ford stuff is new to me. I love this car and I want to get it perfect. Any help with my learning curve is really apprciated. Thanks.
