I also have a 1995 V6 24 valve duratec, automatic tranny. I had/have this problem and I took it into Ford about 2 years ago. They told me there is a bad seal in the transmission and that they want to replace my whole transmission. Well, needless to say, I didn't replaced the transmission. It still gives me a little jerk from 1st to 2nd. 2 years later, and I am at 168,000 miles. And it still does it. I won't replace the tranny until I can't get it into gear. Why fix it if it isn't broken. Yes, it is kind of annoying, but it's what - $2,000 for a new tranny? This is another common problem for our 1995 Ford Contour. My advice, just drive it. If you change the tranny fluid it may not jerk as hard. But that's your answer, a bad seal. If you want to fix it, replace the transmission.
