2020 Ford F-250 Tremor
My SD tremor before I tuned it would skip gears like crazy depending on how I was driving. My 150 doesn’t skip gears often and when it does it’s just going from 1 to 3 but then hits every gear after. Is that normal on the half ton?
Not complaining as it’s way better than how the sd shifted

My '19 Raptor was the same as you describe your SD Tremor before it was tuned.
My '23 F-150 Tremor is the same as you describe your F-150 Tremor.
It seems that Ford Cleaned up the Transmission Shift timing in the newer models.
The skip shifting was the one thing I hated about the Raptor in "Stock" form, but the tune took care of that and it shifted much better!

That is good to hear! Thank you for responding
 
I heard they changed the algorithm on the newer trucks, mine still skips gears here and there on my 22. I'm hoping they can push a OTA update to change to the newer setup. We will see!

Yes this is normal, it short shifts 1-3-5-7-9-10 for fuel economy.

I drive my truck like a grandpa because gas is getting expensive. Eco-mode with cruise control always. I appreciate what my 10R does for me.
 
The quicker it gets through the gears the better the fuel economy. Adaptive learning at its finest.

My 2022 truck is currently at the dealership for the transmission. The dealership did overhauled the trans and transfer case over 7K miles ago. Took the truck in with 55k miles before it hits the 60K warranty for the drive train and this time they are replacing the valve body. Hope the trans works better.

Funny enough I am at 55k and just had my first real transmission issue. Coming from a stop there was a huge clunk and it went from 1st to 8th and stayed in 8th. Came to a full stop and it did not shift back down until I put it in park. Luckily I was still in my neighborhood. It did one more hard shift skipping from 2nd or 3rd to 8th after that, but then was fine the rest of the way to work, ~25miles. Hoping they can sort this out before I am out of the factory warranty.

I would definitely have them make a special note in the paperwork that this is possibly a pre-existing condition and have somebody sign it or something so down the road you can fight them when they tell you to f off if something happens.

Good thinking recording the event
 
The dealership called me yesterday (17th) and told me the tech is going to replace the torque converter and the part won't be in till Tuesday. I wonder what he found wrong with it. Maybe got damaged when ever the trans bang hard. I'll post the invoice when I get my truck back.

For my 2023, upshifts are very smooth for me in every mode. Usually it will only go 1-3 under very light throttle. But if I give it more than even 10% throttle, it will hit 1-2-3.

Downshifts for the most part are completely smooth. However, I seem to get some hard shifts/clunks in the following scnearios (in normal mode):

- Occasional clunk/bump on the 4-3 downshift when very gently braking to a stop. If I am firm on the brake pedal, usually it will downshift something like 6-5-3-1. It unlocks the torque converter as soon as it feels the stiff brake pedal and the downshifting is very smooth. However, under light braking in the same scneario it might do 6-5-4-3-1. I feel like the clunk is mismanagement by the shift strategy when unlocking the torque converter (i.e., it delays unlocking the torque converter until its too late). I will add that I only ever notice this when the transmission is at operating temp, which is why i suspect the torque converter lockup strategy is the culprit, as when the transmission is cold it will prefer to stay unlocked.

- Occasional clunk when abrupty on/off the throttle at low load/low RPM situations. This is most common in 6th gear when im coasting around 20mph, and you go on/off the throttle lightly. You can feel the driveline unloading and loading itself presunmably when the torque converter clutch snaps back in.

- Firmer shift/thud on the 10-9 downshift under medium load going up a hill. Basically if i were coasting in say 10th gear at low rpm around 45 mph, then i come up on a hill and very gradually increase throttle input, when it finally downshifts to 9 it will do this firm/with a slight thud.

Personally, I am not overly concerned about this as it seems to be mostly related to the shift strategy programming, and the fact these modern transmissions with more gears love to lock up the torque converter very early on and modulate it throughout all gears. In the past, torque converters often didn't go into lockup until you were steady cruising at 45+ mph. To my understanding this helps a lot with fuel economy/efficiency, but it makes the torque converter lockup strategy quite involved and complicated, which is why the adaptive learning is so important to help with fine tuning fluid pressures. I will add these types of clunks/shifts never happen in sport or tow/haul, which is much much more deliberate with the torque converter lockup strategy and also keeps the revs a lot higher. Also, the clunks are minute enough that if my stereo is on I can't really notice them at all, so I'm not too concerned with the longevity of the transmission, knowing that the 10R80 is definitely designed to handle more abuse than the occasional clunk. Also, not sure how many of the clunks I feel can just be attributed to normal slack/play in the driveline from the transfer case down to the rear end.

My transmission was mostly fine with the exception of what you mentioned with the low load/low RPM situations. The on off throttle while in traffic it seemed to not like.

Truck has been at the dealer since the 16th. Parts are supposedly in (they couldnt tell me what they were specifically) and the technician is just now starting to work on it. We will see how this goes. Still thankful this happened while still under the factory powertrain warranty and on a non busy street. A few hundred feet further and I would have been making a left across two lanes in a 50mph zone.

That sucks to hear. What happened??

Edit: just read your previous post, my bad

Truck is back! They replaced the valve body and reflashed the transmission. If it were to fail at this point it would be a transmission overhaul.
