Jerky between 2nd to 3rd ir 4th gear, once u pass 45mph its great. Replaced the actuator under air-box cause that's the code I had, p07a3 now code is still pending. Could that be a fluid issue? I turned the actuator with a screwdriver 14 times and dis coke back quickly. Sprayed cleaner in there still same. I did not do anything with the actuator below.

A P07A3 is usually caused by a malfunctioning clutch actuator or faulty clutch actuator fork. The TCM can also cause this.

Check out the images (below). Please let us know what you find.

Yes, that's the one, it's the dual clutch transmission.

Do you have any pictures of the sensor and where it's located as in the picture?

But when I searched for this sensor it says everywhere that it's a code starting with 8, like p0871.

Is this the same car you did the shift actuators? If so, it sounds like the clutch is bad or the clutch forks are not returning?

I turned it with a screwdriver, and it did return like it should. Yes, I changed one actuator under the airbox.

Also, the actuator I bought was from Amazon. I bought one for the 16 Focus I have and it solved the issues.

Did you change the actuator on top? Also, I have seen the TCM go out and cause this as well. This is common. Here is how to change out the TCM. Check out the images (below). Please let us know what you find.
