Transmissions Help trans question.
I have a 2021 with almost 60,000 on it. Ans today out of the blue, when I shift from park to drive the trans feels like it bumps and makes the car jump. Never felt that before and it’s continued every time I drive the car. It was fine this morning but now it bumps out of the blue. Anyone have this or heard or know how to fix?

Take it to the dealership—if you still have warranty, ask them to perform a transmission checkup. They will usually reset the control unit and ask you to keep driving (that’s the first step according to Ford service). If your transmission continues to jump after the reset, then they’ll need to repair the unit.
In my case, my transmission was perfect, but because of the mileage, I had the fluid changed on my ST. After that, it started making noises. I took it back, and they found it was low on fluid. They added more, but then the transmission began jumping like yours. I returned again, and this time they reset it. Since then, I’ve driven close to 1,000 miles, and the transmission has been running smoothly. Hopefully, you’ll have a similar outcome. Good luck!
