Why is the Ford Fiesta's automatic transmission jerking?

I recently purchased a brand new Ford Fiesta and have noticed that the automatic transmission has been jerking a lot. This has been happening since day one and it's becoming frustrating. Any suggestions on how to fix this issue?

I had the same problem with my Ford Fiesta and it turned out to be a faulty transmission control module. I suggest taking it back to the dealership and having them check it out.

Make sure to check your transmission fluid levels. Low levels can cause jerking in the transmission.

I have a Ford Focus and had a similar issue. It turned out to be a faulty speed sensor. Have it checked out by a mechanic.
