Sorry if this is in the wrong area. My in laws just gave my daughter a 2000 focus se. When taking off from a stop the car jerks, stutters, bucks, as if I were driving a stick with no clue as to how to drive it. When they got the car. It had a jasper and they swapped it with another focus due to this issue. The issue remains. It now has the same trans ford installed on 2000 focus. I am thinking the modulator is bad or out of adjustment? It's been forever since I messed with any trans issues. Just trying to get some ideas and figure out if it will be worth it to keep this car. It was free and this is her first car, however I don't want to sink a bunch of money into it. I still have to get it state inspected and that may cause issues as well depending on what they find that may need fixed before it passes. I just would rather not have to pay ford to look into this trans issue. Thanks for any help or advice!
