Torque Converter not disengaging?
A few times I've experienced an issue where the truck doesn't want to stay stopped at a stop sign/light. I really need to hold the brake or it wants to go. Doesn't do it all the time, it's only happened a few times. I have less than 1000km on the truck. It's a 2020 with 7.3 gas engine and 10 speed.
Is this the torque converter not disengaging or something in the transmission? anyone else had this happen?

These 10 speeds are a different animal for sure. The high idle thing has always been a thing. What I'm having trouble with is the transmission constantly "adapting" which makes it unpredictable seeming. The truck also tends to move more than others I've had after putting it in park. The roll after lining up under the trailer hitch is infuriating, both 20's roll a solid couple inches in park! Also had it back itself into a wall when parking, I parked within an inch of the wall, put the truck in park, took my foot off the brake, and it rolled back uphill right into the wall! Never had these problems with the old 6 speeds, and never had the truck move more than could be easily compensated for when hooking a trailer.

I’ve just got mine (7.3 10speed) but I’ve noticed the same thing. It’s annoying for sure. I haven’t tried it yet but I wonder if after engaging park if I left my foot on the brake for a few seconds if it would do it?

1-2" of movement after put the vehicle in park is normal for any vehicle I have ever driven. When lining up to a trailer hitch, always use the parking brake, and you will have zero movement. If you park within 1" of a wall, then the truck moves an inch, that is on you for parking too close.

It could be worse I suppose. My 2020 F550 has Fords genius "auto-neutral" thing combined with hill start assist. So at every stoplight, the truck puts itself in neutral and holds the brakes. Light turns green, put your foot on the skinny pedal, and nothing happens, then a second later the transmission slams into first, the brakes release, and you lurch away from the light after everyone else is halfway through the intersection and the guy behind you is wondering what the heck your problem is. Truck is absolutely impossible to drive smoothly in town! In some ways, I miss my 2016...

I have had the forceful roll backwards and up hill no less. Just about hit another car and I will admit I pinched a hole in the seat. I get the roll due to the parking pawl in an auto but how the hell is it rolling UP hill and with some force?

I tried a launch the other day and it was a mess. Between the engine nanny's, hill start assist, and neutral idle, there is absolutely no spooling the turbo before take-off to get a good launch from a stoplight in these trucks (not that an F550 is made for that, but it was never a problem with my 2016 F550).
