2024 XLT FX4 Vibration from Stop

[NAVYSAR06]

Hey yall. I purchased this truck just a month ago and noticed after purchase there is a vibration/shudder from a stop until shifts into second. Thought it just needed to learn and would resolve but hasn’t improved. I’ve read this was issue with the 5G but haven’t seen anything with these 6G posted yet. Any ideas?

I felt the same in my 2.3 XLT. It was very slight and I thought it might be driveline angle related. My dealer spent some time with it, compared it to others on their lot and deemed it normal. In fact, they claimed it was better than others they tested.

If it bothers you, have the dealer check it out, if nothing else to give you peace of mind.

I also feel that the transmission hangs on to torque converter lockup too long, causing the engine to lug on light acceleration. I took care of that by installing a Roar Pedal performance throttle controller. After thinking this through, I believe a change to the transmission calibration would propably correct all of these issues. I told my service manager that I will be on the lookout for bulletins addressing this in the future.

Something to think about: the Ford Performance Procal tuner might also help. I heard that the changes included new transmission mapping. Can anyone confirm that?

Edit: I added some other thoughts to my original reply.

Thank you for replying. I’d say mine is not very significant either; very mild. It’s funny you mentioned the tuning. I had the dealer install the Ford Performance procal but have been hyper miling in eco mode to see what I’d average. I’m now guessing without definitive proof that the procal tune solely affects the normal setting. Today I left it in normal and can barely notice the shuddering.

Im now reconsidering even taking it in to be looked over. Wouldn’t want the dealer shimming or tinkering with it and it getting worse or some new issue occurring. Thanks again

Me too. Noticed it towing our camper this weekend. I’m going to call the dealer tomorrow. Did anyone take theirs in??

We experienced this exact scenario when towing our 3800lbs camper. On accel from a stop, it feels like a vibration in the driveline. Dealer saw irregular shift patterns in the trans, so pulled and completely rebuilt it. Still having the same issue. I'm curious as to if there is a TSB for this just yet.

not that we are aware of but the procal does do something to the shifting in the 2.3 trucks (and probably all) because mine has never had a shudder or vibration and i have had the procal on for over 10k miles, would be my guess
