My thunderbird just started making a whiney noise, once it's warmed up when I accelerate. The engine idles smoothly, but doesn't appear to shift smoothly. No hesitation or abnormal noise when idle. Runs fine for first three miles. Two probably unrelated things that I will mention anyway...I just put in 1040 motor oil yesterday and my cigarette lighter stopped working Sunday...I know probably time for a new car, but I like my bird! Advice?
