Also on braking you can feel the car clunking back from 2nd to first almost every time. It's almost like you are being kicked forward. At first I thought it was a tune issue but I removed it and still have the same problem. I don't know where to go from here because I was not satisfied with the shops work so don't want to go back to them almost 3 months after install. I'm wondering if this has happened to anyone else and what could be wrong. Another note is that I do not hear any gear whine and under hard acceleration the issue is not as noticeable .

Hey guys,

I think you should touch base with your Service Manager about this. He/she’ll be able to let you know if work or replacement parts are needed and whether there is coverage available (warranty, recall, etc.). Let me know the outcome.

You should also check in with your dealer, McCarthy. If you need further assistance, don’t hesitate to PM FordServiceCA.
