10 speed shifting issue
2022 PSD will hesitate shifting from 3-5 like it momentarily goes into neutral then shifts to 5th gear. Usually light throttle around 20 mph. Engine temperature seems to have no bearing on it. Goes to dealer next week. Anybody had something similar?

this might save you hours as the dealer.

Well known thing. Light throttle = weird shift. Moderate throttle = smooth shift. Someone here said it's the torque converter unlocking for the shift.

Thanks I seem to remember something about that now. Did a search but came up with nothing.

If the dealer can't fix it or a reflash doesn't change anything the next step should be verifying the fluid level. There is no dipstick so you have no way to tell but erratic shifts are a symptom of too much or too little fluid in the 10Rs.

Same here on my '23. The 3 to 4 shift just feels different than all the others. Oddly enough my '15 with the 6-speed did the exact same thing, but I never had any transmission problems with it.

I posted this on another thread, but I'll do it again...
My 2023 does the same thing. I had it in the shop for something else, and went ahead and mentioned the shifting anomaly... supposedly they rebuilt or replaced the valve body, but it did not change it's behavior.
I don't know about the torque converter thing (unlocking) but that seems unlikely. In my case, it usually does it after the truck has sat for at least a few minutes, hot or cold. I am in and out of my truck all day, with 5-20 minute service stops, and it will almost always have that 3-4 slip on the first gear change once I'm moving again... and then usually won't do it again until the next stop/start cycle.
Here's what they did with mine...
I say 'supposedly' worked on my transmission, because I see NO evidence that they went into my transmission. Something is fishy in Denmark...

@Charlie98 there should have been LC3Z-7F396-C Pan Gasket on that invoice along with LC3Z-7G186-A Filter if they dropped the pan and valve body.

I remember hearing about Ford having a plastic dipstick to replace the trans fill plug...

Wait a minute, are you telling me that the fill port is not accessible on any of the MY20s and up? I thought it was from what I've seen. Obviously you have to crawl under the truck to check it. So if it's not accessible, how did they fill it at the factory?
